Got these two coins at different times and places. As you can see, even though they have the same date and denomination, they are subtly different. The left one says "朝鮮" (Korea) while the right says "大朝鮮" (Great Korea). This would have been just after the Sino-Japanese War (1894-5), so a lot was going on politically as it shifted from being a vassal state of Qing Dynasty China to a falling under Japanese influence. Oddly, both types seem to have been minted for multiple overlapping years. Korea: Years 502-505 (1893-1896) Great Korea: Years 501 and 505 only (1891 and 1896) Great Korea: (different variant): Years 504-505 (1895-1896) I'm not sure what the difference between the two "Great Korea" types is. All three types seem to have been minted for year 505 (1896) Anyone able to hazard a guess as to what is going on here, and why the two different names for the country were used? Oddly, the coins are different colors, as if they used different copper alloys. The examples on Numista show a similar color difference. Any advice would be most welcome! I know there are a couple Korean coin experts on this forum from time to time. Thanks.
