The best-priced as cards, a row of them; every other ad as a line, by ask. Each ask is the seller’s own number; the platform’s mark opens the listing. Each one says when we last confirmed it at its source: the price and availability are from that visit, so check the marketplace before you go.
eBay GermanyPrice history
Every recorded sale, one point each: 33 of them, placed by the day the ad went up. Too few sales to draw a trend through them without inventing one, so the points speak for themselves. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.
