Watch List notes:

Danish West Indies, 40 cents, Christian IX, 1905, encapsulated NGC MS 65. KM-80. A superb white gem of one of the most popular Caribbean coins, with every prooflike detail sharply defined (rare thus) and all fields smooth with a minimum of bagmarks, a level of quality that is usually considered "specimen," hence among a mintage of just twenty pieces according to KM. Note that another "specimen" example (not slabbed) sold in May 2017 for the equivalent of $4400 with buyer's fee at Rasmussen Copenhagen Auction 871 (lot #105). Tied with two others for finest known in NGC census. NGC #3813786-009.
($3000-4500)
