Just a video I made on three prototype coins on display at the "Money Museum" in Seoul. These coins were the first ever to be made in Korea from sketches, to models, to reductions to strike. All previous Korean coins required foreign contracting at some step in the minting process. These coins are the "ancestors" of all later Korean coins that did not rely on another country's help. I made this video since the museum re-arranged its exhibits and decided to display its two copies each of these coins in order to show both obverse AND reverse sides of the coins in the display case. They only have ONE of that bigger coin, the 2,500-Won pattern, so now only the building side of it is facing up at viewers. I took a photo of its reverse 4 years ago, so now I have images of both sides of all three of these prototypes!
