Would you happen to have a South Korea 1970 10 Won coin? I'm looking for the Bronze version. The Korean minting authority (KOMSCO) started to make this coin in bronze (88% copper/12% zinc), then switched to brass planchets (65% copper/ 35% zinc) the same year. I'm looking for the bronze type. I'm ONLY looking for one in the higher MS-grades (red), and with "good" eye appeal.
