check_serialread-onlyWhether 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
find_star_runsread-onlyThe 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.
list_serial_patternsread-onlyThe 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.
