Block 78 alpha
A block 78 sat that starts a bitcoin: 390,000,000,000 + k × 100,000,000 for k from 0 to 49, fifty sats in all.
How a sat qualifies
The row's definition is Block 78 and alpha. An alpha is a sat whose number is a multiple of 100,000,000, the first sat of a whole bitcoin. Block 78 holds sats 390,000,000,000 to 394,999,999,999, 50 BTC, so it has exactly 50 alphas: 390,000,000,000, 390,100,000,000 and so on up to 394,900,000,000.
The first, 390,000,000,000, is also block 78's first sat, an uncommon. Block 78 is in the vintage range, so every Block 78 alpha is also a vintage alpha.
Why collectors care
Block 78 is the block mined by Hal Finney, in the site's description, and it is not tracked whole: its alphas, omegas and palindromes are the sats of it the index follows one by one. Fifty alphas exist, and that will never change.
