Dietrich IV was the ruler of the Bishopric of Dorpat in what is now modern Estonia from AD 1413 to 1441.

Denomination : Silver schilling.

Reference : Hal. 292.

Size : 18.0 x 19.8 mm. Weight : 1.29 grams.

Grade :  VF with weak areas (over all really a gF).

Obverse : Crowned bust of Dietrich, with DERICVS EPVS around (or similar).  Some of the letters are weakly struck and I may have miss-read them.

Reverse : Arms of Dorpat (crossed sword and key), with MONETA TARBAT around (or similar).

This particular issue tends to be fairly carelessly struck with weak inscriptions.
