So why should there be 14 notes in a Colonial Currency Collection? Because in addition to at least one note from each colony, you will want one or more Continental Currency notes.
Continental Currency notes were issued through the Continental Congress and helped finance the revolutionary war. Please see the attached note
Ben Franklin printed many Pennsylvania and Delaware notes. Importantly, his nature unique leaf prints on the backs of notes were effective counterfeit protectors. His business name appears on notes printed in 1764 and earlier. He had a partner named Hall who teamed up with Sellers after Franklin's retirement from the printing trade. Pennsylvania also used the New York City trick of issuing notes for specific government expenditures. The Insane Asylum Note (actually the Walnut Street Jail) and the Lighthouse Note raised money for public works and community infrastructure such as jail buildings, piers, and lighthouses.
