S. Korea 10-Won Date Variety.

I recently noticed that there just might be at least two different varieties of the 1973 South Korean 10-Won coin. This semi-key date coin seems to have something approximating a "small date" and a "large date" variety. In the coin on the left (the "small date"), the "9" curves more, and stops at about the same level as the bottom of the "1." In the "large date" (right), the "9" is straighter and plunges more noticeably below the bottom of the "1." The "7s" also look different, with the top of the small date angled upward, whereas the large date seems straight. You can also see some "machine doubling," if not some actual "doubling" on the back of the "3" in the small date version. If you just eyeball the two coins, side by side, you can see some size/shape difference in the dates... Fascinating...
