This model on the price scale0.003 to 0.6 across 6 published values

The same six decades as the front page, so a price is in the same place here as it is anywhere else on this site. The two marks in the accent colour are this model’s cheapest and dearest published values.

Price history

Every distinct value this price has taken, oldest first — what the price did, not how often we happened to look. Rows marked backfill came from a public git history of a third-party pricing file and were never verified by us; they extend the series backwards and are flagged rather than hidden.
