Thanks for all the mintage information guys. Windjc I did have a couple of lengthy calls yesterday with some investors and they just have smaller investments in mind with collectables. Of my group of friends I was the crypto enthusiast back pre $650 BTC or so. Now at $1.22 M for 25 BTC asset with less liquidity than an exchange wallet I understand the enthusiasm is less than a few years back. I am a little more of a collector and drool over these cool collectables but like a lot here I'm not 25 btc wealthy and can only admire you guys that were able to hold so long. This is a museum piece ! Smithsonian piece ! I think its worthy of a call to see interest there 
Well that's an interesting idea for sure. But with museums, they don't purchase most items. You donate for a tax write off. So if I donated it to the Smithsonian I could take an appraised value of it and write that amount off against earnings for a year. Then the extra bonus is getting the personal acknowledgement for the donation.
It would be interesting to see at what point in the future they would be interested in a piece like this. Certainly once BTC is at $1 million value and this piece is worth north of $25 million. And of course, Bitcoin would need to be accepted more mainstream and as a reserve currency. I suspect in 10-20 years that would be an option. Maybe sooner.
True, someone with north of 200 BTC might find that appealing for all the reasons you stated. Great recognition for BTCC as a company and their insight in recognition of a block as a collectable as well. I remember going to the Smithsonian when I was a very naïve 18 year old and being in aww of all the gems in a room with The Hope Diamond. I asked the guard by the case " Are These Real?" I remember him smiling and going "Those are real" lol, memory of a lifetime to me... I believe they would have some interest now BTC gets a lot of MSM exposure now. Best of luck with this ! no matter what you decide its a winner
