These coins will cost a lot even in China and congratutions for your nice collections! Thanks for sharing!
Those ARE cool! I collect South Korean coins (1959-present). The Koreans made similar coins like these around the time of the Qing Dynasty based on these designs (cast coins), but I don't want to get into collecting them as many of them are too expensive for me, and I don't want to deal with being extra diligent about authenticity. Cast coins really scare me in regards to authenticity.
