Certified Proofs of Connecticut (Box 1)
About the Project
In cities including Hartford and Stamford in Connecticut, currency was issued from national banks - but not before being certified by the Bureau of Engraving and Printing. A practice from 1863, certified proofs allowed the BEP to ensure intaglio printing plates were accurate before currency was printed.
