Why this number?
The typical used price is the median of 11 used sales observed in the last 24 months, with outliers removed and the figure rounded. An observed sale is often the last asking price rather than a confirmed hammer price.

| Most sold between | €95–€120 | 25th to 75th percentile, same window |

Price history
Every recorded sale, one point each: 205 of them, placed by the day the ad went up. The line follows the middle of the sales around each point, with the middle half behind it, and breaks wherever nothing sold nearby. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.
