      About these prices

      Each point is one sale of tracked sats, found on chain by the fork: a marketplace listing or an accepted offer paid in the same transaction. Its price is the marketplace's: on Magisat the listing price, the seller's payment plus Magisat's 0.5% seller fee since September 2024 (the buyer's fee is not in it), and for an accepted Magisat offer the payment plus half the fee output; elsewhere the seller's payment plus the marketplace's fees. Sales with no marketplace fee in the transaction (OKX's, among others) are Unknown.

      The unit price is the price less the sold output's own value, per sat of a row. Each sale is of one row, the rarest that holds all the sats it sold, so rows don't overlap: Uncommon is plain uncommons (a 2012 uncommon is an Alpha uncommon, a rare sat a Rare), Block 9 is block 9 chunks (a 450x chunk is 450x). A bundle that mixes rows is of its rarest row. A label row, such as Block 9, 1st tx (a label within Block 9), has no market of its own: it lists the sales lying in it, each as its own row. Include rarer sub-categories also shows a row's rarer sub-categories, such as the alpha uncommons under Uncommon: lighter, priced per sat of the row, named by their own, and outside its median and market numbers. A sale that splits sats out of an output counts only the sats it sold. A sale for no more than the output's own value has no unit price above zero: it is in the table, not on the chart.

      The line is the row's median unit price over the 30 days up to each sale. Outliers, drawn hollow, sold for over 10 times or under a tenth of the median of the row's previous seven sales: a fat finger, a wash trade, something else in the output. They are left out of the line and the row's market numbers. Inscribed sats carry an inscription, whose value is not the rare sat's: hidden unless you include them, and never in the line.

      Rare

      The first sat of each difficulty adjustment period: the first sat of a block whose height is a multiple of 2,016, other than every 1,260,000th.

      How a sat qualifies

      Bitcoin retargets its mining difficulty every 2,016 blocks. Ordinal theory makes the first sat of each of these periods rare: the sat with offset 0 in a block h where h is a multiple of 2,016.

      Tiers are exclusive, and a sat keeps only its highest. A height that is a multiple of both 2,016 and 210,000 is a multiple of 1,260,000, the start of a cycle, so its first sat is legendary (or, at block 0, mythic), not rare. Every other multiple of 2,016 gives a rare. Halving blocks that are not cycle starts are not multiples of 2,016, so an epic sat is never also rare.

      The first rare sat is sat 10,080,000,000,000, the first sat of block 2,016. A rare is also never counted as uncommon, although it is the first sat of its block.

      Its neighbour

      The sat just before each rare is the last sat of the period's final block: a black rare. Each rare has exactly one, so the two categories always have the same total.

      Why collectors care

      Only one block in 2,016 starts with a rare. Some rares also carry other types: sat 50,400,000,000,000, the first sat of block 10,080, is a rare that is also a Kilosat uncommon (a milestone sat), and many are alphas.

      How many

      Will ever exist: 3,432. Mined so far: 482. Extracted, held alone in small outputs: 165. The rares of 2009 are on the Rare category filtered to that year (see 2009).
