Black Sats are the second most popular rare Sats category, only after the Uncommons Sats. They are widely adopted by the Ordinals community in general, and their total supply is exactly the same as Uncommon Sats. Just as Uncommon Sats, their rarity is related to the position of the Satoshis inside the blockchain, and this makes its rarity properties much less subjective and much more clear then the other Sats categories, which is one of the main reasons for their value accrual and adoption. Black Sats are the Satoshis that come right before each block - in contrast to Uncommon Sats, which are the first Satoshi of every block. 

Vintage sats are satoshis that were mined in the first 1000 Bitcoin blocks.

Vintage black uncommons are vintage black uncommons that are from the first 1000 bitcoin blocks, and so their total supply is 1000. It is expected that a very low amount of these early sats will ever be attained by rare sat collectors, since most satoshis from the first blocks of 2009 haven't moved since they were mined. Satoshi Nakamoto (or some other Bitcoin early adopter) has mined them and stored them in a Bitcoin address, and they remain in this same address until today. The only way to get them would be if said miner would go to their 2009 wallet and spend them.
