Oh, I see. Checked out their site. I read something about using copper in minting and they just plate the other portion with precious metals. Relating this to our Bitcoin physical coins, how do we know that these coins are purely made of what they say it is? Some additional questions. 1. How do we authenticate each coin? 2. Do they have a unique serial number? 3. What is this HOLO? 4. What does it mean to be tamper proof? (I think I read this on a Holo coin auction, I am not sure) Note: I'll probably compile all the questions and answers made here, and insert the proper attribution to who answered which, later when I have time to do it. Too busy reading informative stuff I got from you guys. Hi Factmine, Here is a brief response to your questions, based on what I have learned over the past 8 months: Some additional questions. 1. How do we authenticate each coin? - You can have the seller post pics of front and back of coin with the seller's username and date. Then go to the uberbills site where I provided a link to. Here is an example of a Cas Coin's description from uberbills: https://casascius.uberbills.com/?address=12CS4Z1ZhAefHkGrumrsS9gvHCKJK13V1tFrom there, you can get the full address and check any blockchain site to see if the coin is still loaded.(There are other links to other coin companies, like Kialara and Titan, but I would start with Casascius, because of popularity and history). 2. Do they have a unique serial number? - yes. It is a combination of numbers and letters that reveal the first bits of your public address (aka public key). Other companies will engrave the public address on the coin itself. 3. What is this HOLO? It is short for the hologram sticker that conceals the private key. To get to the private key, you have to peel the hologram. You can then redeem the coin. Nearly all coin companies use the hologram method to hide the private key. 4. What does it mean to be tamper proof? (I think I read this on a Holo coin auction, I am not sure) - tamper-evident means that, once even a little bit of the holo is peeled, it will be evident that someone tampered with it. Thus stay away! The private key may have already been revealed even though the uberbills site shows that the coin is still funded. Probably a scam. The main reason Mike Caldwell made these coins was to show a physical representation of bitcoin. One of the ways to spread the word is to make something tangible that stores value and sell them. These coins act as a pretty effective way of cold storage (as long as you believe the coin maker doesn't have access to the private keys ) I have learned a boatload by reading lots of threads and participating in the forums. (Don't forget Google.) Be careful, Factmine. This hobby can be habit forming

The most popular physical crypto is the Casascius. A couple of other good sites that tell you info on them: http://www.spotcoins.com/bitcoin/casasciusThis will give you a good idea about mint counts, etc. Another site to verify if the Cas coin is still loaded: https://casascius.uberbills.com/By inputting the number/letter combo from the hologram, you can learn a lot about the particular coin. I am learning new things every day, so I appreciate your post!

With less than 20 hours to go, TMAN has the high bid of 1.3 BTC
|
|
|
This is a quick auction, ending Tuesday, December 6th at 6 PM EST, which is 11 PM Forum time. There are fewer than 440 active 2011 v2 Casascius 1btc out there, and this could be yours if the price is right! You will notice that the holo does have vertical scratches as well as a spot at 5 o clock. The coin came in the plastic package that is in the second image. My guess is that is what caused the damage to the holo. Shipping is provided by me. If you would like to use escrow, you can use minerjones or another agreed upon escrow. Buyer pays fees. Otherwise, payments go to this address: 12Dgsw144xERVz11CTKPwsnGEzefjbUjnK The specific coin on uberbills: https://casascius.uberbills.com/?address=16fMKmh3jeVVTiBmUYz6jcJ5yeS2oxvAbaAuction RulesStarting bid: 1 BTC Increments: .05 BTC Shipping: to be paid by winning bidder. Ending time: Tuesday, December 6th, 6:00 PM NYC time. (11 PM Forum time) Sniping: Bidding within 15 minutes of ending adds 15 minutes to the auction. Payment: Expected within 48 hours (can be negotiated further beforehand) No new accounts that are less than 1 month old. If the forum experiences downtime, I reserve the right to add time to the auction. Good luck to all!

Ill offer $200 per coin, escrow with OGnasty would be cool
You do realise that Kialara Golds cost $249 each to begin with, nearly 2 years ago? They have been selling anywhere between 1.2 and 1.75 BTC in the last few months, with Vizique willing to pay 2 BTC for one for a special customer. $200.. You must be joking I had no idea on the price. I thought 200 was overpay so I editted my post to 150. I didnt mean to insult anyone. I just added up the prices on the website. Ill retract it. But I was just saying to myself that I wanted a complete kialara collectoin a few days ago It's for only the ones that are sold out. If you've noticed, any physical crypto, whether it's Casascius, Titan, etc. gets a premium for sold out coins

Are you serious?

PM sent.
I'm guessing you're going to get a lot of pms! (One sent from me as well )

All settled. Locking thread.

As I have not heard from jlbit, either via this thread or via pm, the highest legitimate bidder is Zepher at 1.95 btc. This auction is now over.

Not that I really care, but you could probably help absolve yourself of any more undue suspicion by giving this newbie a chance of more than an hour. I mean, I usually give 24 hours on auctions. That said, it is your auction, so do as you please. Thanks.
I understand you point of view, owlcatz. But the high bidder has not even messaged me or updated this post. He is now AWOL.

Well, I gotta learn from this...From now on, NO newb accounts with less than a month activity! @jlbit, I need you to show my escrow, minerjones, that you do indeed have the funds. Otherwise, your bid will be invalidated. (It won't count) Please PM me the proof once available. thank you. Same here. If proof can be provided, then your bid on my auction can stand as well. @jlbit, because you are a brand new account, I will require that you have one hour to send payment to the address in the OP, and that you post the txid on this thread. Otherwise, the coin goes to Zepher.
