500 Riksdaler Banco / 750 Riksdaler Riksgäld

Sweden ran a dual-currency system through much of the nineteenth century, with Riksdaler Banco (the bank's own unit) and Riksdaler Riksgäld (the state's paper currency) circulating simultaneously at a fixed but unequal rate — three Riksgälds to two Bancos, approximately. This note carries both valuations because holders needed to know the equivalent in either system, not because two separate promises were being made.

Sveriges Rikes Ständers Bank, the precursor to the Riksbank, was at this point still formally owned by the Riksdag rather than the Crown — an unusual constitutional arrangement that shaped how note issuance was authorized and debated. The dual denomination inscription is the real curiosity here: a direct artifact of that monetary awkwardness, frozen in the typography.
