02 / THE SOURCE RECORDS
Historical prices & changes
Latest collections and earlier references appear together, newest date first. Expand a collection to see exact face values, all card conditions and comparable price changes. Missing dates from 13 September 2026 through the latest collection are filled with labelled estimates: linear interpolation between available daily reference bounds, or the last reference carried forward when there is no later price. These estimates do not affect calculator rates. Ranges span different conditions.
