Why these numbers?
The span is the range of per-version medians behind the middle 80% of the 187 sales recorded under this name in the last 12 months, so a rare version at either end cannot stretch it. 4 versions have the 8+ sales needed to carry a median of their own. The median of all those sales together is €65. That mixes every version into one number and is not a value for any one of them, which is why it is down here. 2,938 sales on record all-time.

Priced too low to take at face value
This one is at half the usual price or less. More often a part, a copy or a mistake than a bargain. We show them, but look before you go.
