| Tool | Description | Behaviour |
|---|---|---|
| check_serial | Whether one US paper money note is worth keeping, from its serial number: the Federal Reserve Bank, the series (worked out from the serial when it is not given), every collector pattern in the eight digits with its exact odds, and for a star (replacement) note the print run it came from with the number of notes printed and its rarity band. Covers Federal Reserve Notes from Series 1963 on. Gives no price and no authenticity judgement. | Read-only |
| find_star_runs | The smallest US star note print runs on record, smallest first (top 10), optionally for one denomination, series or Federal Reserve Bank: the notes printed, the rarity band and the serial range to watch for. Runs printed only for uncut collector sheets, which never circulate, are left out unless include_sheet_runs is true. | Read-only |
| get_coverage | Which denominations and series the star note print run figures cover, with the Federal Reserve districts and number of star runs on record for each, the sources, the date of the last update and any known gap. | Read-only |
| list_serial_patterns | The 17 fancy serial number patterns collectors look for on US bills (ladder, solid, radar, repeater, binary, birthday, low serial and the rest): a strict definition, an example, how many of the 100,000,000 possible eight-digit serials match, and the odds. | Read-only |
