so these were made in China? Under permission from Caldwell or no?
Only 5 1000 BTC coins were minted so either these were done himself or Mike did them as some sort of memento.
It looks like someone quoted above stated there are 50 Series 2 coins made, not sure if that is accurate.
There were only 5 main funded 1000 BTC Gold coins ever made, there was 1 prototype or sample i guess am not sure
and these non funded(2 factor) coins which were 50 mint as stated here by mike himself
