Duchy of Warsaw, Frederick August I, 3 pennies 1810 I. S., Warsaw mint, VERY RARE
A very rare variety (practically unheard of in the trade, most likely a trial minting of a trojak) with an inwardly curled triple ending in a ball and with a pattern of the numeral "1" in the date with a split ending of the main part, completely unheard of on trojaks and groszes of the Duchy of Warsaw - a pattern reminiscent of the typeface of numerals from the 18th century.
Rarer first vintage trojak, a variety with narrowly spaced date numerals and widely spaced initials I.S.
Copper, weight 8.25 grams, diameter 25.7 mm
