Watch List notes:

Philippines (US administration), silver Wilson medal (so-called dollar), 1920. HK-449. 38 mm Only 2,200 of these "Wilson dollars" were struck in 1920 to commemorate the opening of the Manila Mint, a branch mint of the United States Mint. In early 1942, as invading Japanese forces approached Manila, many silver 1 peso and 50 centavos coins along with a small number of Wilson medals were dumped into Manila Bay. This recovered example is UNC with minor saltwater corrosion (mostly around the edges) and has a protected area on the obverse from another coin resting on top during its time underwater, some cleaning hairlines noted on the front. From: "Manila Bay treasure," dumped off the Philippines in 1942
($400-600)
