I have been involved in the bitcoin community for a while now, but for the interest of privacy I have created a new account to post this.
There is very little regarding sales of funded 100BTC Casascius bars, is there still interest in these or has the value risen so much that they are completely unaffordable? Are there users on here who help connect buyers with sellers, or is it all done via the public forums? What would be the current going rate for selling these items for BTC?
I really appreciate any help or advice that you can give. Most of the posts I have seen are very outdated at this point. Thanks!
There's always someone richer, so 100BTC bars certainly are not nor will ever be completely unaffordable. It's a small market though. Something like 50% of Americans can't make an unexpected $500 payment. And USA has the highest national net wealth. I digress.
There is no "going rate" because any public auction is few and far between. I believe around 2015 Casascius (Mike) helped a friend sell a 1000BTC coin, at the time around $2 million or so. Was a public post on Collectibles. This is all pure recall so details may be off by quite a bit. Someone else would need to confirm.
Easiest is to simply create an auction here. You would be better off using your original account with established history/reputation. It would also help to have a PGP signed custody history from Casascius (proving he sold the bar to you directly).
