The physical Bitcoin, graded MS-67 by PCGS attracted the attention of over 200 bidders who were actively tracking the auction, with over 10,000 page views. The final price represented a $49,700 premium over the price of Bitcoin at the time that bidding ended.

The 25 Bitcoin "Baby Cas" was graded by PCGS alongside the holy grail of crypto physical coins – the "Gold Cas", a 1 Oz. Gold Casascius coin with 1000 Bitcoin or BTC. The current value of the "Gold Cas" exceeds $60 million and is by far the most valuable coin in the world, despite being issued only 10 years ago by a private company.

Casascius, the company created by Mike Caldwell issued physical bitcoins from 2011 to 2013 in various denominations from 0.1 BTC to 1000 BTC (the "Gold Cas"). Over 800 of the 25 BTC denomination coins were produced, and less than half of that remain unredeemed.

Ian Russell, president of GreatCollections said "as expected, there was a significant amount of bidder interest for the most important physical Bitcoin ever to appear in auction. We had new bidders register from 14 countries specifically for the Bitcoin auction, not to mention the interest from the traditional numismatic community."

It was the second most valuable coin GreatCollections auctioned this year. The finest 1893-S Morgan Silver Dollar realized $2,024,024 in August – an all-time world record for a Morgan dollar. Also in August, GreatCollections reported being the winning bidder for three of the most valuable U.S. coins to ever appear in auction for over $21 million – the finest 1804 Silver Dollar, the tied-for-finest 1794 Silver Dollar, and finest of two known 1861 Paquet Gold Double Eagles.

I’ll be the first to admit I’m simply astonished that Physical Bitcoins are on their way to being not just among, but the most valuable coins in the world. What a development!

Hell ye! That’s what I was hinging last time. If the US Mint adopts crypto into to their coins it would rejuvenate coin collecting hobby. This is the next step in coins saga/coin collecting.

Kaiser Wilhelm

I don’t understand, Victor, and I swear I’m not playing dumb here, but I haven’t a clue as to how bringing physical representations of Bitcoins and other Cryptocurrencies into the numismatic fold would in any way enhance the hobby of coin collecting. That being said, I’m happy to be informed as to how this would work. Thanks.


I think you would agree with me if say the hobby as it is, is not popular with young people. At the moment, everything is going digital. So why not spice it up?

Kaiser Wilhelm

That’s an excellent point, Victor, that I don’t mind admitting just hadn’t occurred to me. I think I’m so wrapped up in my septuagenarian retired world outlook that I tend to overlook all the other generations aka age groups that are essential to the hobby.

If physical cryptocurrencies can attract subsequent generations to numismatics then more power to them; it goes without saying that I would enthusiastically support that. Big kudos to you for developing and sharing that thought among us here, and by the way, many thanks for replying to my original question.

Sure no problem. I like precious metals and all but I think we are headed in the direction of business coins and paper money being discontinued in favour of digital/crypto. Lincoln cent is first. The day will come when no one will buy collectors money because they just wouldn’t know it exists. If people at the US Mint had 2 brain cells left they would advocate for incorporating crypto, otherwise they will see reduced sales and vaults full of alloy metal 1 dollar type coins seating there collecting dust.

Kaiser Wilhelm

Thanks, Victor.

Whether your predictions are right or not I doubt that they will come about in my lifetime as I am now 74. Therefore, whatever does happen down the line isn’t even potentially all that real for me. On the other hand, for a much younger individual it would be a much different situation in that for them the digital/cryptocurrency world may well be the one they have effectively transitioned to. Lastly, for someone even younger than that that it will quite possibly be the only reality they have themselves ever experienced.

Kaiser. Who are you leaving your collection to? I’m 43 with 10, 8, and 5 year olds. One of them will probably take good care of my small fortune.

Kaiser Wilhelm

Goodness, Victor; my son is 45, my daughter is 43, and my grandchildren are 14, 13, 10, 7 and 6. I honestly have no idea what to do with my collection. Maybe I could split it X number of ways.
