Census and research data.
I am looking to start a group to cross share census and serial data with each other.
Anyone willing to cross share BEP data would be great as well.
It looks like uspapermoney.info is not going to be updated any further ;c(
It would be great to have some sort of a repository for collectors to look up stats on their notes.
Census work is very daunting, I can say that first hand.
