33 1/3 Riksdaler Banco

Sveriges Rikes Ständers Bank — the Estates of the Realm Bank, precursor to Sveriges Riksbank — issued this denomination as part of a deliberately fractional system designed to bridge the gap between smaller and larger Riksdaler Banco notes. The 33⅓ figure is not an accounting oddity: it represents exactly one-third of 100 Riksdaler Banco, a clean fraction in a monetary framework still anchored to the old Swedish counting system where 48 skilling banco equaled one riksdaler.

The twenty-one-year emission window coincided with Sweden's prolonged transition away from the Banco monetary standard, which was formally replaced by the Riksdaler Riksmynt system in 1855 — rendering this denomination obsolete within two years of the series closing.
