Why these numbers?

The span is the range of per-version medians behind the middle 80% of the 33 sales recorded under this name in the last 12 months, so a rare version at either end cannot stretch it. 3 versions have the 8+ sales needed to carry a median of their own. The median of all those sales together is €45. That mixes every version into one number and is not a value for any one of them, which is why it is down here. 593 sales on record all-time.

Versions without a page of their own are read from the model code sellers put in the title. Where we have too few recorded sales of a version to quote one honestly, the column shows what sellers are asking for the ones up now instead. That is a hope, not a sale, and asking prices run above what things fetch. A dash means we have neither.
