I tried to check a few of the BTC addresses on the backs of the coins but couldn't get any to pass a checksum. Seems like they're alternating between large and small letters as capital/lowercase. My guess is a misread some of the characters because it's tricky to see in the images.

Do you have any of the correct addresses handy?

That is something I do need to add to my notes, I will take a closer look in the next few days and attempt to work them out.

For an extra .25BTC i will carve your bitcoin address and/or QR code into the reverse side of the coin as well as carve out a recess if you would like to store the private key to that address.

The buyer will receive a CoA (certificate of authenticity) from me usually within 1-2 weeks of receiving the artwork. As many of you who have bought my art already know, i use Bitcoin technology and Vanity addresses on my CoA's and it can take up to 2 weeks to generate the desired result.

I believe the original buyers sent their own addresses in to be put onto them (maybe not the 1Unity vanity address). Also nobody did send me their CoA although two of the owners did mention them. I will reach back out to the ones I can get ahold of and see if they made their own public address or if WC created them.

Definitely a poor choice to have all caps font and to just make the supposed lower case letters 1 point smaller than the uppercase.
