Why these numbers?
The span is the range of per-version medians behind the middle 80% of the 19 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 €390. That mixes every version into one number and is not a value for any one of them, which is why it is down here. 382 sales on record all-time.
