Just providing some provenance for my 2011 Series 1 Casascius 1 BTC coin

[JohnGalt]

As of June 28, 2021, I own the Series 1 Casascius 1 BTC coin with the address beginning with 17E9BEio. I bought it from an anonymous person in 2013.

If we’re doing this, it should be in a different part of the forum IMO. Otherwise Collectibles will be littered with thousands of these. And, there’s no reason so many people need to look at it. Nonetheless, beautiful coin!

Not a bad idea to have a single thread that anyone can post their coins in...maybe price is they feel like it. Good to have all this info somewhere.

I don't think there are enough holders willing to do this where it will really be a problem and it could be useful in the future for someone looking to buy these coins to be able to find people holding them.  I like collectible porn.
