Maybe not fakes, could just be repurposed casascius coins. With a clearer picture I'm sure krog would be able to tell for sure.
It’s def a fake. If you zoom in you can tell pretty easily. Biggest tell is the lines going across the coin are way too thick, esp for a 2011 brass.
Edit: Now this is another new find where it was repurposed like the Serps-
https://imgur.com/a/xu0pOnxI got this one.. and looks like the remains of the holograms from the album you posted.... wonder how many different Cas they used?
I don’t believe they actually used Casascius blanks. Here’s the sales thread -
https://bitcointalk.org/index.php?topic=245613.0They state in OP “You buy and receive, physical brass 1 bit-coin tokens, in the style of Casascius”.
They then state “As I said, it is token blanks of the casascius coins that they are stuck to. They are 2011 blanks with '1 bitcoin' on them- that people will be able to reuse afterwards to load with a bitcoin themselves. It is quite common for bitcoin blanks to have 1 bitcoin on them. However I can always change the style of the token, but I notice that many people on the forum are asking for 1 bitcoin token blanks.....we need to keep our product viable and appealing across all markets so this was the token of choice”.
The picture I posted is certainly a Casascius fake as well as he said “Casascius like”.
Are you sure your hologram is from the Co?
