Where can I find historical (very old) USD printing data? Where can I find historical/very old USD printing data? Charts can be useful, but I want numbers. It is for a project.
The Bureau of Engraving and Printing maintains public records on their web site, but that data only goes back to 1980. Therefor your best option might be to write or call them and ask for information for the time period you're interested in. If they are not forthcoming, you can call back and try your luck with a different staff member. If that doesn't work, you can resort of filing a Freedom of Information Act request. According to this page the average turnaround time is 23-31 days depending on the complexity of the request. 

There is also this site, which has information on the US money supply from 1959 - present, but I am not sure it is presented in a way you'll find useful for your project. I am also unsure if it meets your definition of "very old." 

Good luck!
