Theres a lot to the chemistry of tarnishing, but in short the main reason silver tarnishes is humidity and sulfur in the air. Its tough to give guarantees on how things will tarnish, but the typical course is if you have a low humidity environment with sulfur and no oils and salts from your grubby hands, you're more likely to produce silver oxide compounds that'll give you that pretty rainbow tarnish you see people selling for too much money. I don't know in particular what the specific chemical reaction is, but if you touch coins when they tarnish they're far more likely to end up black and dirty looking. Morgan silver dollars are really well known for having that pretty tarnish because they were stored for years in bags at banks with desiccants to keep them dry, but the bags were treated with sulfur to keep insects and rats away.

The aluminum foil method you use is sort of the reverse of electroplating. Instead of a plating solution you're creating an electrolyte solution with the baking soda, and theres a difference in electronegativity between silver and aluminum that creates a tiny voltage that makes the sulfur compounds on the surface of your silver break off and form bonds with the aluminum instead of the silver. I don't actually know if thats a good way to clean your coins or not. Its not abrasive, but the reason people don't use chemical dips for example is it will eventually remove the mint finish that comes with the striking process at the mint by their polished steel dies. I've dipped silver coins before melting them in harsh jewelry cleaner and the effects weren't visible. Without spending a lot of time researching exactly what constitutes damage to the finish of a coin removing the sulfur through electrochemistry may or may not do similar damage and it may not be immediate.

@Salty - we spoke about this topic a few times over the years. I think you said ruthenium would be too hard to make coins out of? Maybe Iím mistaken.

Yep, while ruthenium is a platinum group metal, its more refractory than platinum which is itself already relatively difficult to work, the same reason premiums on platinum coins tend to be significantly more than gold/silver. Platinum itself wasn't a very easy to work with metal until starting in the 1980s groups of jewelers spent 20+ years developing best practices on how to work with it. As far as I'm aware, theres no standard for ruthenium outside of very specific niche applications ie machining mesh for catalytic converters or something of that sort. There are specialty ruthenium ingots out there, but you'd never find a mint to work it as I doubt the type of dies, strikes, etc needed to work it are commonly available knowledge.

Artisans can make some really neat stuff like coins out of amber, but try asking them to make you 100 and best case scenario they give you a couple year lead time. Craftsmanship is to be respected of course, but its a hard sell getting a customer to buy a coin for $1000 when its $30 of material and $970 of labor.
4  Economy / Collectibles / Re: Coin Materials on: April 11, 2022, 03:08:48 PM
There are a lot of cool materials suitable for making coins, but interesting alloy blanks aren't widely available to mints. Electrum like you brought up is a workable enough material but its just not commercially available. Specialty materials could be done, but it just would have to be very small batches by artisans rather than mint struck coins. I do a lot of metalwork myself and I end up having to alloy everything myself because even though some alloys are just vastly superior in all regards to what we'd consider the standard, they just aren't vanilla enough to be commercially worth it for big companies to change their ways.

The blanking process requires ingots of the metal be poured, the metal is then rolled into sheets of a uniform thickness and cut out with dies into blanks. If the alloy doesn't have machinable properties like most old alloys that were simply cast and hammer struck, they'll never be available for people to make coins from.

Goat sold a 1000 BTC Casascius coin on here a few years back. I'm not sure where the thread went but I recall the trade details were partially disclosed.

Just a quick tip about the dimensions you're planning, Gold Eagles aren't .999 gold, they're 22 karat. If you try the same dimensions with pure gold, you'll get some odd mass.

I'd be a buyer of this and potentially whatever else you're planning on selling if you change your mind and decide you're willing to use escrow.

Seems to me that the whole thing is based on the lockdowns. Hospitals and clinics in March, April, and May, were not letting babies get in to receive their scheduled shots.

My point with regard to your post above this one^^, is that if the kids in November-December had not received their shots, there would have been even fewer SIDS deaths.

Are you sure that the kids got all their regularly scheduled shots during the lockdown?

Cool

How do you qualify the decrease in SIDs to one a single part of the lockdown? SIDs is linked to just regular colds, if you can establish a decrease in the exposure to the common cold and other illnesses due to blanket lockdown measures, you could also claim that thats the cause rather than lack of vaccination.

Fish are able to change sex to adjust an imbalance in the sexes. It seems that humans are going for the same ability. Smiley

Well, a lot of fish are able to change their sexes after birth. I believe with humans, its stress hormones effecting the fetus and biasing the gender. At least from an evolutionary standpoint, stress means conflict, conflict means males dying, replace them or the species dies out. Things that take millions of years can't keep up with boom sticks that fire projectiles.

Since this is the case (I presume), all it means is that if the kids hadn't been vaccinated in November-December, there would have been such a dynamic drop in SIDS that we could for certain blame the vaccines for the SIDS deaths.

Cool

I'm not sure that I'm following 100%, but what you are looking to see is if changes in routine vaccination schedule due to covid results in any difference in pregnancy outcomes. To this point, there has been no routine vaccination schedule change for any babies that have already been delivered. I did a quick google search because my only background was that when I get a flu shot, they ask me if I'm pregnant, to which I always respond yes, and it pisses them off. Anyway, between that, and a quick CDC guideline that said make sure your MMR shots are up to date before becoming pregnant, leads me to believe that they don't normally give you vaccines while pregnant. If we're just talking about the US, routine vaccinations were still in place in March anyway, maybe April or later in some places. What that means is that anyone who got pregnant before April (more realistically May) received all of the regular vaccinations that they would have normally, so any babies delivered until 9 months after that date is just a regular ole vaccine exposed baby like the rest of us.

While I doubt that we'll see the outcomes you're expecting, I'm with you in being interested in how covid effects birth rates, etc. Will many of the children born be male, will there be a new baby boom generation because couples have been stuck home with nothing better to do, will being exposed to covid or the covid vaccine result in tails and horns, lets watch!

That said, I'm pretty sure you can get vaccines again. For my routine medical procedures over the past few months, they've just been only allowing one patient in at a time, and ask that you wait in your car and they'll call you to come in rather than having people sitting around in a waiting room, so I'm not sure what 2-3 months of delays in vaccines will do.

Catch this:
The U.S. has already witnessed a 37 percent drop in cancer care diagnosis compared to this same time period last year, and we have experienced massive drops in cancer screenings including mammography (87 percent drop), colonoscopy (90 percent drop) and Pap Smear (83 percent drop).
What is going on here?


There is a study that I have misplaced that talks about people with Covid having a reduction in cancer. It seems that Covid plus a certain nutrient/medicaton is curing cancer.


Cool

Uhh, you mean people aren't going into the doctor for routine visits that would otherwise catch the cancer that they have. They don't give you vaccines if you are pregnant, meaning there has been no change in vaccine schedule for any data collected on premature birth/SIDs in the past 9 months. All of the babies born before November-December of this year have been subjected to all of the routine vaccinations that their mothers would have normally received. Data from pregnancies after November start to become significant on analyzing effects of covid on pregnancy.

I will throw out another interesting thing to watch out for, and thats the sex ratio of children born. During periods of high stress, war/famine/major economic/social problems, there is a major shift in the male:female ratio of children born, favoring female rather than male.

Its been suspected for quite a while now that covid can mutate fast enough so the concept of immunity is null. Whats not currently known is how much past infection helps prevent reinfection and how long to expect the antibodies you do produce to stick around. There have already been suspected cases of reinfection. People have tested positive and been hospitalized on separate occasions months apart after testing positive for covid19 both times. It can't definitively be claimed yet though, as its possible that the first infection of covid was weakened by the patients immune system, but then regained strength and knocked them down again rather than reinfection.
12  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 02:58:23 PM
Yeah so I reread the thread, and I think I figured out why I'm confused. OGNasty puts a $ value into a ticker and it updates the price in BTC. It was someone else who claimed the whole, 10% increase in BTC price you made money on the refund statement. Lines are getting crossed here.
13  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 02:05:14 PM
yes there is

he states that everything is priced in USD but it is not. people that paid in btc were refunded the same amount of btc that they paid not the USD equivalent - that means it is not USD based.

the site needs to be clear - he cant claim one and do the  other and then insult anyone that says anything about it

Yeah, what you're saying is not acceptable and has been the subject matter of many lawsuits, if I'm not mistaken starting with BFL. You pay Bitcoin not USD. The bitcoin just happens to have a USD value which has fewer daily fluctuations than Bitcoin. If you are selling a commodity and don't want to enter into a contract to sell it at 50% under what you paid for it by accident while you sleep because an exchange got hacked or the CEO of Bitcoin goes to jail (  Grin ) you peg your prices in fiat. OGNasty was selling coins for $1750 worth of Bitcoin. If the trade never happens, you're entitled to your Bitcoins, not USD. What you're saying is completely unreasonable. Bitcoin is Bitcoin whether it has a USD value or not. If a trade doesn't happen because he runs out of stock or whatever, his obligation is to make you whole and refund your purchase price. You didn't give him $1750, you gave him $1750 worth of Bitcoin and are entitled to your Bitcoins back, not the fiat equivalent. In 10 years of trading here, I've seen verrrrrry few cases where people have explicitly stated that the transaction would work the way you are expecting it would, and I've seen verrrrrry many scammers try to play this card. It isn't an accepted method of trade by the community.

I'm pondering what the legal implications would be for someone operating the way you suggest OGNasty should have. I'm not certain here, but I believe that would make you an illegal money transmitter. Instead of doing a commodity > commodity exchange, you're exchanging their commodity to USD and would be remitting to them USD then exchanged back to BTC in the event of a refund. Just make purchases with the intention to cancel because you think the price of BTC is going down, and you've successfully shorted BTC.
14  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 03:46:27 AM
again - it does not say cash value and that is the issue. If it said cash value, yes. If it was how it is now, no.

Yeah, it doesn't seem like there is actually any problem.
15  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 03:43:32 AM
the only post i saw of yours was talking about my refund - i didnt have a refund as i  didnt purchase - my point is how it is listed, yes because it can affect a refund. and that is my point. Your statement was about me getting a refund. so yes, you missed the point the first time.

Let me pose a question then. Had you purchased a coin, and bitcoin doubled in value between your purchase and when you got a refund. Since it said cash basis, would you have been happy receiving half of your BTC back? That is generally one of the easiest ways to get labeled as a scammer. A handful of people have tried pulling that and its never gone well for them.
16  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 03:30:54 AM
Righto, I was mixing info from multiple threads. So that makes it easier because I potentially empathized with people who may have needed to fight for a refund for whatever reason.  Who cares if the site states the USD price? If you go to place an order and they're using an exchange rate you don't like, don't buy it. If the ticker was stuck, using an exchange rate you don't like, or whatever else, you could have not bought it and moved on, or requested an updated total, etc. How is it any different from having a sales thread where you say you're selling a camera for $700 and then when someone decides to take you up on it, you look up the BTC price and give them a BTC address and total? There was a thread where OGNasty said they were selling a coin for $1750, so they converted that to BTC and posted it on the site. OGnasty may have used an autoupdating ticker, or maybe done it manually? Regardless, the solution to your problem was pretty minor.




you have missed the point.

in the big picture what it is priced in can and often will affect how you get refunded. Take bitmain for example, you pay them 2600 in btc for a miner based on the exchange at that moment because they price it in USD not btc - they convert it yes. If you get a refund, which is rare - but I did get once - and even though I paid in bitcoin, and was refunded in bitcoin, the amount I got back was based on USD value of bitcoin at that time.

so whether something is priced in btc or usd matters when there has to be conversions.

No, I didn't miss the point at all, I actually posted about that first, but was told that wasn't a concern. People would rightfully crucify OGNasty if they did what you say Bitmain does. If you pay anyone BTC and they don't give you back the same BTC in the event that the trade is canceled, they're a scammer plain and simple, unless there is a very clear and established contract stating otherwise.

Not my thread.  I was just clarifying some things if you read the entire thread. Wink



Yeah I was addressing the OP
19  Economy / Collectibles / Re: Nastyshop on: July 31, 2020, 12:18:09 AM
No offense, but while you may have a valid claim about the refund process, complaining about whether they have their prices set in USD or BTC is kind diluting whatever claims you make. Why does it matter in the slightest whether they have their asking price pinned to USD or BTC? Was there an issue where you paid in BTC and your refund wasn't the same amount in BTC? If I decide to sell a coin and pin it to crude oil, but accept X barrels worth converted to BTC, who cares? Now, if there was an issue where you paid BTC and got refunded a different amount, fair enough.

(I did get my coin I ordered, and I also asked ahead of time before ordering because the thread said that quantities were limited and they updated quantities on saturday)
