Yearbook unlisted at Onebid auctions, one listing in the archive from the transferred former WCN archive from 1997. 25 years ago!!!! An interesting type of coin related to Poland, described in Kopicki under 11587 with a rarity grade of R1. First vintage minting. After the death of Krystian (the eldest son of Augustus III), he was succeeded by his son Frederick (later Prince of Warsaw), but until he came of age, his uncle Xavier ruled on his behalf. Xavier was the younger son of August III (younger brother of Krystian). When minting coins, he did not include the Polish-Saxon coat of arms on them, but gave the title of Polish prince in the legend. Xavier was decorated with the Order of the White Eagle.
