eBay United StatesPrice history
Every recorded sale, one point each: 77 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.
