The earliest type is described under Thaler (q.v.). The name was applied to the new coin on account, of its value being equal to that of the gold Gulden, and because up to the time of its appearance no silver coins were in circu- lation of a larger size than the Groschen. In Latin documents of the sixteenth cen- tury they are generally referred to as Unciales, from their weight, which was one ounce.
The name Guldengroschen was soon ab- breviated into Guldener; the coins were popular for a time but were eventually superseded by the Thaler. See Florin.
