Sweden 1785 - Stockholm Spinnhus Pollett System – Complete Nine-Denomination Institutional Currency Set (One Half Öre to One Daler)
This complete nine-note ensemble represents the entire internal monetary system of Stockholm’s Spinnhus, the women’s correctional institution and workhouse operating on Långholmen Island during the late eighteenth century. Produced circa 1785, these engraved pollett notes functioned as closed-economy institutional currency, issued exclusively for use within the prison environment. They served as a controlled medium of exchange through which inmates were compensated for labor, particularly the spinning and processing of flax and wool. Internally, the notes operated as proto-fiat currency, enabling regulated transactions, discipline, and subsistence within a self-contained penal micro-economy.
