Korea - 100 Mun, 1866 - Museum Gallery

Here's another example of the Korean 100 Mun. I acquire more of these that I think may be authentic to the State mint because there are nearly 50 varieties. I've yet to find a definitive source documenting these in a way that a 'westerner' can use to discern them. Rubbings do not cut if for me. I will link a Korean site below that indicates that most for sale are fakes. This one is 39.5 mm and weighs 27 gms. This makes it right in diameter but a bit heavy according to KM 143 (24 gm). In this photo has the Obverse/Reverse images are flipped.

Sang P'yong T'ong Bo, Hojo Treasury Department
Korea, ca 1866. Obverse Image: Four Chinese characters read top, bottom, right, left Obverse Text: Romanization: SANG / P'YONG / T'ONG / BO (Translation: Always Even Currency). Reverse Image: Character for Hojo Treasury Department at top, denomination read right, left, bottom. Reverse Text: Romanization: HO / TANG / BAE / CHON (Translation: Character for Hojo Treasury Department, worth one hundred).
This is a One Hundred Mun ("Value Hundred" tangbaekchon or dangbaekjun [sang pyong tong bo] coin.
The One Hundred Mun is the only denomination of sang pyong tong bo coinage for which accurate mint records exist. These coins were first cast by the Treasury Department on December 12, 1866 and put into circulation beginning January 15, 1867. The last coin was produced on June 16, 1867 which means these coins were cast for only 172 days. A total of 1,784,038 "One Hundred Mun" coins were cast by the government.
In general the One Hundred Mun coins minted by the government have a diameter of 40.6 mm, a thickness of 2.8 mm and a weight of 25.1 grams. There are about 50 varieties of the 100 Mun coins with differences so slight (character stroke style, size, etc) it is hard for a Westerner to discern. See my other examples here in the Moneta Museum.
