1/2 Frederick d'Or - Frederick William IV

The half Frederick d'Or denomination had an awkward existence in mid-nineteenth-century Prussia — too small for major transactions, too valuable for daily commerce. Frederick William IV's reign saw persistent tension between a modernizing Prussian economy increasingly tied to the Zollverein's commercial demands and a currency system still rooted in Frederician-era gold coinage. By the 1850s, the writing was effectively on the wall for the Frederick d'Or series; full decimal reform was less than two decades away, and mintages of the fractional gold issues contracted accordingly.
