Vintage
Any sat mined in the first 1,000 blocks (heights 0 to 999): sats 0 to 4,999,999,999,999, the first 50,000 bitcoin ever mined.
How a sat qualifies
A sat is vintage when it was mined in one of the first 1,000 blocks, heights 0 to 999. Every one of those blocks paid a 50 BTC subsidy, 5,000,000,000 sats, so block h holds sats h × 5,000,000,000 to h × 5,000,000,000 + 4,999,999,999, and the vintage range is sats 0 to 4,999,999,999,999: the first 50,000 bitcoin. Membership is a pure function of the sat number; no other property is needed.
Several of the site's historic blocks lie inside it: Block 9, Block 78, Block 286 and Block 666, and four of the 19 Nakamoto blocks (9, 286, 688 and 877). Their sats are vintage too.
Why collectors care
These are the oldest sats there are: the site's own description is "mined in the first 1,000 blocks". The range is fixed and fully mined, so no new vintage sats will ever appear.
What is tracked
Five trillion sats are too many to follow one by one, and the index does not track the vintage range whole. It tracks the vintage sats that are special on their own, and counts them in four rows:
- Vintage uncommon: the first sat of each vintage block (sat 0 excepted, which is mythic).
- Vintage black: the last sat of each vintage block.
- Vintage alpha: every vintage sat that starts a bitcoin (a multiple of 100,000,000).
- Vintage omega: every vintage sat that ends a bitcoin.
A vintage sat that is none of these (a vintage palindrome, for example) is in no vintage row. All of Block 9 is tracked, as its own row.
How many
All of these are mined.
