18 Pence / 1 Shilling and 6 Pence Colony of Pennsylvania

Pennsylvania's 1773 emission was authorized under an Act of Assembly dated March 20, 1773 — one of the final colonial currency issues before the Continental Congress effectively took over paper money policy during the Revolution. Hall and Sellers, the Philadelphia printing firm run by David Hall and William Sellers, also operated the Pennsylvania Gazette, and their press handled official government printing work throughout the 1770s. The fractional denomination reflects Pennsylvania's practical approach to small-change shortages, a chronic problem in colonial commerce where hard coin disappeared rapidly into trade deficits with Britain.

The 1773 notes were among the last Pennsylvania colonial issues to carry the anti-counterfeiting botanical impressions pioneered by Benjamin Franklin decades earlier — nature-printed leaf patterns whose vein structures were considered essentially impossible to replicate by hand.
