As a resident of the city of State College here in Central Pennsylvania, I was surprised to learn that years ago this city was home for a US National Bank that issued money. The photograph below depicts a US $20 National Currency note issued by the First National Bank of State College in 1929.

National Notes were issued by banks who received a charter from the US government authorizing such banks to issue money. The Government Printing Office printed these notes with the same design as other US currencies with the exception of including the name of the issuing bank, signatures of the bank officers, and the charter number. National Currency notes were printed in the US between 1863 to 1929.
I have to wonder if this currency innovation might be repeated in the US sometime in the future.
