Are any numbers available for the number minted? Is there a max total that will be made, or just however many are ordered? Is it possible to know how many of the 12.5's were made?
No, we don't have an artificial cap for the 6.25+ BTC Bitcoin Blocks. However, in practice, there is a limit, as these blocks can only be made until the next halving to 3.125+ BTC.
For the last batch before the halving, we sold 24 of the 12.5+ BTC Blocks. (Those serial numbers were: AA013001 through AA013024.)
Hope that helps!
thanks,
Bobby
