my current ballet collection -
https://streamable.com/9ymgz0There are a handful that I am still missing.
1. 24k gold plated First Day of Issue REAL Bitcoin
2. 24k gold plated REAL XRP
3. 24k gold plated REAL Ethereum
4. Bitcoin Block 12.5 BTC
5. Bitcoin Block 6.25 BTC
6. Litcoin Block 12.5 LTC
7. FirstBI Exchange
8. REAL Digibyte
9. REAL ZG
That last 6 will be harder to get, partially as some of them are quite expensive due to the load value and no longer being made. Would settle for peeled BTC blocks even. And the last 3 were not publicly released.
If anyone knows of any others that are out there and not in my collection or in the list above, please let me know!
