A Danish gold medal of Frederick V (1723-1766), issued in 1749 to celebrate 300 years of the House of Oldenburg, is expected to auction for around $27,404.

The lot will feature in the online sale of the Georg Baums collection at Fritz Rudolf Kuenker, which will close on March 13.

The gold medal was produced under the reign of Frederick V to celebrate 300 years of the House of Oldenburg

It was engraved by Peter Christopher Winslow, who created many of the designs for coinage in the state between 1747-1752.

It features a profile of King Frederick on the front, while the back displays polaris above the globe, along with various Latin inscriptions.

The medal bears a number of small scratches with an error at the edge, but is an otherwise superb example of this rare issue.

A gold medal produced in the Polish city of Danzig in 1646 to commemorate the marriage of Wladyslaw IV to Maria Ludovica Gonzaga, princess of Mantua, carries an identical estimate of $27,404.

The engraving shows the couple seated and shaking hands, while their weapons lie on the ground - indicating the joining of the two houses.

Two years later Wladyslaw died, and Gonzaga married his successor John Casimir.

A 1762 Russian gold medal, produced on the promotion of Count Alexei Bestuzhev Rjumin to field marshall, is also valued at $27,404.

Rjumin was a major influence in the court of the Empress Elizaveta, and directed Russian foreign policy for a significant span of the 18th century.
