While I'm here, going to share another incredible set.
A family, separated by hundreds of thousands of generations, reunited.
The BTCC 25 BTC Error Block is a 1-of-1 manufactured by BTCC back in 2016. It contains the block reward for blocks
418419 and
418427.
It is the only error block in that series, and contains 50.71528925 BTC.
I also have it's great-great-great-(way too many greats)-grandchild, the Ballet Halving Block from 2020 - This contains the block reward for block
650648, totalling just over 7 BTC after transaction fees.
The photos aren't great, but if there's enough interest I can get them out of their safe space and do a higher quality shot with some other pieces.
