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,

Just to clarify on one point: The next halving is some ~4 years away, and though the current Bitcoin Blocks (6.25+ BTC) are not technically limited in production, we CANNOT commit to having them for sale indefinitely.
If the orders keep coming in, then of course we would like to keep selling them for the next ~4 years.
However, these are highly-priced collector pieces, and the demand is limited.... so it's very likely we'll stop production and sales at some time well ahead of the next block halving.
This means that if you have an intention to buy the current 4-star Bitcoin Block, then please don't make the mistake of waiting 1-2 years, expecting to be able to buy one. It may not be available by then.
Just FYI.
thanks,
Bobby
