I can’t seem to find any information on these three 100 won notes that recently came to me as part of a small collection. Any insight as to year(s) and/or value would be appreciated. thanks!
There's a note on ebay that looks similar to your third note. Seems they have dated it at 1947. https://www.ebay.com/itm/144305098769
Look like late 1940s notes issued before the establishment of the Bank of Korea in 1950. The issuing authority was the Bank of Chosun, a Japanese colonial government financial remnant that continued to operate under the U.S. military occupation of southern Korea (Sept 1945 to June 1949). See "Pick Numbers" 29 through 46. These are obviously in that Pick Number range.
