The Friedrich d´or was a Prussian gold coin (pistole) nominally worth 5 silver Prussian thalers. It was subsequently copied by other North German states under their own rulers´ names (August-, Friedrich-August-, Christian d´or) and valued at 4.8-5 silver North German thalers.
It was used from 1741 to 1855 as a regularly-issued gold trade coin at this time, and was traded at a small premium or discount to its face value of five thalers in silver standard currency (silberkurantgeld) used in the stock exchanges and elsewhere. Around 1780, for example, the Saxon August d´or was quoted at 116 to 120 groschen sächsischen silberkurantgeldes (4.83 to 5 thalers, Saxon silver currency), with a maximum discount of 4 groschen (0.17 thaler). In the 19th century it usually had a low premium.
