Bitcoin Forum

For the next few weeks I plan to auction a few coins from the Encyclopedia of Physical Bitcoins and Crypto-Currencies that are somewhat obscure and have been hard to find. For those of you trying pick up one of everything you can find, these next few coins may be fun additions to your collection.

This auction is for a 2013 Antaui Woldcoin that is graded by IGC, MS67 Prooflike, loaded with 5 Worldcoins.
500 were made, it is 1 oz .999 silver and it is featured on page 64 of the Encyclopedia. By the way, usually in forum auctions, discussion is discouraged for the sake of the sale. However, I am encouraging discussion. These threads always end up adding to history of these coins. If you know something, please share.[/i]

The value for 5 WDCs as I write this is a whopping <$0.17. So, the value is in the scarcity of the coin not the load.
I have not found any evidence that these were issued with public addresses; i suppose all information is covered by the hologram.

500 were made. There are not many threads in Bitcointalk on Antaui.
Here is one of the better discussions on the forum around this coin: https://bitcointalk.org/index.php?topic=3119210.0 (https://bitcointalk.org/index.php?topic=3119210.0)

Cool coin ✌🏼

Have not seen one in a long time and gotta say this hologram was always one of my favorites.

 Goodluck with the auction!

Thanks Krogoth. I suspect you have one of these.

Someone peeled it for the huge value of 2 or 3 cents a Worldcoin?! Makes no sense.

it was not I that peeled it, nor do I know who did

Yep, I was just lamenting the thought process of the original peeler. However, a nice add to the collection.

I had a couple of conversations with forum members about Antaui's keys. This is all anecdotal since they do not have a website or since no literature from them exists that I have seen; however, all of these coins seem to have been preloaded with 5 WDC. No public keys were issued. So, owners could only peel and redeem using the private key. That's the theory until someone offers up better verified info.

as an fyi - the WDC QT wallet does not recognize the private key on the peeled coin that I have - says "Invalid private key encoding (code -5)"

The Antaui key appears to be compressed as it less than half the length of the keys I have generated from the QT wallet.

Would be interesting to see if you are willing to add a photo?

Sorry, I was just re-reading that thread because I've not read through it since, well, 2014.  One user posted their price (in WDC) which was 82 WDC each.  That might not sound like much but in late-2013, that was about $40/each.

Thank you. Web.archive is a new find for me. Very cool site. I think we shoudl create a thread that links the original websites to all the coins.

Here's a link to a post in that thread where Gudmunson provided a list of addresses to the coins.

I also reached out to an ooooold crypto buddy.  There's a small chance he might still have the app or a custom script to decrypt the keys on the back.  I'll post back here if he ever responds.

im out. congrats

That's a wrap! Thank you VernDog for your winning bid. I will send a pm

Also, Thanks to everyone that added details about Antaui World Coins. I saw a comment on the Antaui site that claimed something like, 'We can stop making alt coins now, World Coin is all we need.' That kind of aged like milk, but I will say the Antaui World Coin coin, is a nice little piece of history.

Definitely a nice coin and a valuable part of physical bitcoin history. Sad I couldn't add it to the collection this time. Congrats Vern

Mopar, I am glad you looked under the holo to help us figure out how they worked. Evidently those code were mini keys that required a decrypt program. Here is a quote from the website:


In order to redeem the coins, you'll need a program that has been modified from the bitcoin version to decrypt private "minikeys." I'll be posting that in the coming days. Thanks! gudmunsn

I was never one to make comments like that, but we actually got close.  I was a late-comer to a small team that was building basically a competitor to somewhat new Coinbase.  Everything was working and we had bank transfers and all we needed.  I was brought on to actually write a coin-to-coin exchange.  

Again, I still can't go into details, legally, but we had to shut the company down, immediately days before it launched.  Had that not happened, I think WDC would still be a strong coin.  In fact, we were all major players in the WDC space and I also had a strong design outline to make WDC trim the block chain and allow for headless wallets.   Had we succeeded, the crypto world today could have looked quite different.  But, old crypto history is also filled with a lot of stories like that one so they don't mean much either.

Congrats on the sale!  .007 isn't bad at all. Also, your original post says 17:00EST, and it's 16:24.  You should still have about 30 minutes, no?

Thanks again for adding to the info on Antaui. Sorry to hear WDC didn't reach it's potential. World Coin was certainly a great name. I have been a part of a couple of ventures with a ton of promise that just could not make it over for various reasons. Man, those still sting.

Also, I think we ended correctly. 5:00 Eastern or 17:00, plus 15 minutes due to bids in the waning minutes.
