Does anybody know any sites that I could use to find out the run number of some paper money I have? I know a site to use for star notes, but I need one for regular bills. Thanks!
Same way as for star notes: divide the serial number by the number of notes in a standard run, and round up. For anything printed in the past couple of decades, the standard runs are 6,400,000 for non-star $1's through $20's, and 3,200,000 for $50's, $100's, and stars of all denominations. If your notes are older than that, see the information on standard run sizes here.
