20 Dollars

City Bank was a common name across antebellum America — without a confirmed state charter or city of issue, this note's exact origin remains genuinely uncertain. The New England Bank Note Company, operating out of Boston, was one of the more prolific security printers of the pre-National Banking era, supplying plates and finished notes to dozens of state-chartered institutions across the country. The "S" prefix in the Pick reference confirms this as a scrip or obsolete issue, predating federal currency standardization.

The unspecified date range is typical of notes printed speculatively on commission, held by the issuing bank and signed or dated only upon actual release. Whether significant quantities ever reached circulation is unknown.
