1922-PM Peso, Type I - Straight Wings Variety
All Culion Leper Colony coins were routinely disinfected by the Philippine Health Service. The caustic chemicals used in the disinfection process had an extremely deleterious effect on aluminum. By 1922 it was apparent that the Aluminum Cullion Leper Colony coinage of 1913 and 1920 were just not holding up and a more acid resistant alloy needed to be found. Starting in 1922 all Culion Leper Colony coins were struck in a Copper-Nickel alloy of 75% copper and 25% nickel.
The obverse design of the 1920 Cullion Leper Colony 1 Peso consists of a caduceus, the words "PHILIPPINE HEALTH SERVICE" and the date "1922". The reverse has the denomination "1 PESO" and the words "CULION LEPER COLONY PHILIPPINE ISLANDS". An Incuse monogram "PM" (Philippine Mint) mint Mark is stamped between the "1" and "PESO";
