These pieces were struck as part of a broader Swedish monetary reform effort in the 1840s, a period when the Riksdag was actively debating simplification of Sweden's notoriously convoluted currency system — one in which riksdaler specie, riksdaler riksgälds, and riksdaler banco all circulated simultaneously at different values. The 1/64 riksdaler specie denomination itself was so fractionally small as to be almost impractical, which likely explains why these remained patterns rather than entering production.
