Bitcoin Forum

I made a reddit thread a while back about a coin set I had:

https://www.reddit.com/r/Bitcoin/comments/5lvjjr/check_out_my_casascius_1000btc_gold_coins/

These don't have BTC in them but they are my most prized possession.

User throwawaydev400 made an offer I couldn't refuse to sell him 1 coin. We agreed on a price of 14 BTC about a month ago. We met in person today for the trade. And amazingly BTC price just broke gold parity. What a momentous occasion.

Thought I'd share.


EDIT: Currently selling for 14 BTC

Holy wow.  Coblee you offering anymore up for sale?

Sure, you have 14 BTC? 😀

I remember very nice, that is a cool parity !  refresh my memory where did you get the coins from? you had them made?

Guess thats the lowest huh.  I would rather have one of these actually than a loaded 10cas so its tempting

so when you adding XMR? trying to work out if its worth buying smoothies XMR sets.....

Yeah coblee i know its not the venue but when can we expect xmr on coinbase?

Thanks a lot! Coblee was a great guy and very patient during the drawn out meeting(I'm a bit of a technical noob).

I cant believe you only sold one out of them, you gotta get a new case made now! Do you plan on selling anymore?

Yes, it was hard to sell one, but the price was too good. Now that it is broken, i will sell the rest. Maybe keep a few for myself. Make me an offer, but the market price has been set. 😀 And I'm in no hurry to sell them.

Fantastic  8) I see the photo of this COIN simply beautiful!!!!

????
thanks

The set of these were specially unfunded by mike and i owned by coblee
he has sold one coin which has broken the set and is ready to sell more

He offered these unfunded.  There were only 5 coins sold funded in which you are talking about.  Gotta question though how many unfunded coins were sold

I am waiting for HabBear to show up and offer escrow services...

20 x 14 = 280BTC

That would be an epic return for these coins at current valuation.   :)

Not really. I spent ~100 BTC on each.

If we consider 1oz gold = ~1BTC atm, were you able to buy 280oz of gold for the BTC value spent back when you purchased them?

Yes, but I used BTC at the time to buy these coins. If I had kept the BTC, I would have been 10 times better off.

Why? Spotcoins is accurate with the number of coins minted that were funded, which is consistent with all the other coin types the post numbers on.

They don't post any numbers on the blanks, slugs, or that St. Petersburg coin.

As long as Spotcoins links to Mike's Uberbills tracking site, the counts are accurate and reliable. If you wanted to test it, though, redeem one of your coins and let's see if the number redeemed goes up!  ;)

Well played. Haha.

In honor of the gold parity I recuse myself from the selection of aspiring escrow proprietors available on this forum. I must insist that I not get involved. Don't even think about asking me.

Psych. If the OP was offering a transaction here, I probably would have.

FYI, these coins have BIP38 encryption on the keys where Mike Caldwell doesn't know the password. So the funding address will not be in the list of pre-generated addresses Mike created. So none of the trackers will be able to track these coins.

Nice coins you got there, 1000 BTC Casascius Goldies!  :o :)

Original cost 100 BTC each... Ouch!

If I could afford I'd get one, nice pieces.

Dang I would have thought the opposite.   :o

In any event, they are extremely unique and good luck recouping value from the coins.

Sold.  PM sent.

how much is it going for? i need at least 5

14 BTC

Why would you need 5?  :)

Haha, "I need 5" of the 5 that were originally funded and available? Hahaha.

(I realize that Coblee's set and others were created on special order)

LOL 5 funded would be over 5mil

was expecting less than the price op asked for. but its still a good piece

What's the price you would consider selling it for, including shipping? Is anything lower than 14BTC acceptable?

I've already sold a few coins at this price. So I know it's reasonable. But I will entertain offers over PM.

Can you explain a little more about the 2factor arrangement.
  
Do you know both the private key and the password or just the password to the private key underneath?  Who generated the private key?  If it wasn't Mike, how was the information communicated?

How it works is that I have a passphrase in mind and I generated an intermediate code and gave that code to Mike. Mike cannot figure out the passphrase with that code, but he can generate private/public key pairs that can only be decrypted with my passphrase. He also gave me confirmation codes that I can use to verify that the passphrase matches the public key address on each coin. I will give that confirmation code to whoever buys the coin. This website is useful for generating and confirming BIP38 encrypted keys: https://bit2factor.com/

Although Mike doesn't know the passphrase, I used the same passphrase for all the 20 coins, so I have told the people that I sold the coins to. If Mike finds out what this passphrase is AND he kept the encrypted private key underneath the hologram for the coin, he would be able to derive the actual private key and steal any coins in there. I trust that Mike didn't do that. And if he did, there are a few 1000 BTC coins for him to steal.  :)

That said, I wouldn't put any BTC in these coins myself. The BTC in it will be locked and can only be removed by peeling the hologram, which will destroy most of the premium of this coin. And if it makes the coin harder to resell.

Plans to offer X-mas Layaway?  ;D

Sure, a 20% deposit, and I will hold it for you.  :)

14 btc for 1 oz of gold?

Sounds like a sweet deal for the seller!

Hi, stopping by on a random visit to the forum.

Coblee's gold 1000 BTC Casascius coins are legit.  They are 2factor.  I sold them to him when we met up in San Jose for one of the earliest Bitcoin conferences (I'd like to say May 2013)?  Without looking at my records, my eyeball's recollection was 20 to 30 coins.  He got the single largest delivery of the gold blanks that I had made up in the first place, and in exchange, I got a ride in his tesla (and some random looking digits added to this blockchain thing out there on the interwebs).  I just didn't sell very many of the completed coin at the premium price I was asking, and the more 1000 BTC became worth, the more even trusting ("testing") the 2factor system for the 1st time with your hard mined 1000 BTC becomes a heartstopping leap of faith.  So that's why I made them available that way to Coblee.  I am pretty sure I made no more than 50 of the gold coins.

Very cool, Thanks for verifying such a cool and unique collection. Are you still selling in-person?

Thanks!

That's amazing to hear it from your side and to see that you're still here watching some stuff :)

Exactly.
So what is the current REALISTIC price for these coins?
These are unfunded so some of the quotes I have seen are really out there.
Any updated screens of these coins because all the links on the first page are "server error" when I clicked.
Thank you.

Dont know if he still is but i believe coblee is selling them for 14btc each.  These are iconic coins and if i had the spare 14btc id probably pick one up

beautiful coin save one for me I just cant afford it right now every thing is tied up in something big at the moment but I want one for sure  ;D

coblee did your price change or still the same? or whats the new current price for the coins?

Anyone interested in getting their hands on one of these coins?  I purchased one from coblee as a result of this thread and would possibly be willing to part with it.  I'll accept a little lower than coblee was asking.  :)

Anyway, I thought I'd give a nice bump to this topic and give everyone a flashback from the past when you could sell an oz of gold for 14 BTC (or 100 BTC when coblee bought them!).  A reminder of just how poor of a practice it is to try and value things in Bitcoin over time.  I'd also of course happily accept an offer 14 BTC from anyone in the 1 BTC = 1 BTC crowd.  :D

1btc = 100 million satoshis > gold > cash

Casascius coins have been dropping in value dramatically since I got in. I remember being offered an error coin for 1.7BTC in 2018 (I think BTC was $4k at the time), just seen that one sold recently on this forum for 1.039BTC. Obviously a massive drop when priced in BTC but also a small drop when priced in fiat. I was hoping that they would of mooned by now, but maybe they need more time? 14 BTC for an ounce is just nuts  ;D

Do you have a ruff idea how many unfunded gold coins Mike Caldwell made?

i thought there are only a small bunch of these, however, thanks for the pics!

Someone give this man some more merit.

edit: holy shit the thread is old, whats current days price of coin? and aprox supply number?

One day the last of the remaining loaded Cas coins will be auctioned off at world renowned auction houses and will fetch well over load value...well over.  Crypto has only picked up steam and these are pretty much the first representations of bitcoin and will be a must have for billionaires to show off to their buddies.

At least that's how I see it but who knows.  

GL with your sale
