In 1857, the first ½ Rigsmontskilling coin was introduced. It was composed of bronze, weighed 1.9 grams, and measured 15.6 millimeters in diameter. Depicted on the obverse was a crowned monogram (reading "FVII") with oak branches and the year of minting below. Displayed on the reverse was the value (inscribed as "½ SKILLING RIGSMONT").
In 1868, the coin was reintroduced. It retained the original composition, mass, diameter, and reverse design of the first coin. The only changes made were to the year of minting and the monogram, which read "CIX".
