    Take a look at this 1966 10-Won Coin in NGC MS-63 Holder:


    This one has "full pagoda eaves." This is a diagnostic that I thought up after examining many examples of these 1966 10-Won coins. This was the first year that the South Korean Mint struck its own coinage. They used coining dies made in Britain by the medallist firm, John Pinches Ltd. Often, this particular date appears with the eaves of Dabo Pagoda not fully struck up, making the eaves look "mushy," while the reverse has a scratchy or pockmarked "10," noticeable at the center of the numeral. This was either due to low coining press pressures and/or excessive relief on both sides of the coin in the same general area. Later dates of the 10-Won coin do not seem to have this issue.

    This particular 1966 10-Won coin in the above eBay listing seems fully struck.

    Here are some examples of uncirculated 1966 10-Won coins that are not as fully struck:

    The pronunced blobbiness one has nice color though.

    Yep. These copper coins can tone up to a nice color. They can also grow spots.

    Very cool. Makes me want to look through my coins to see if I have any from '66

    Interesting - I only have one in this date. Don't know if I have spares to check

    I see the weakness in the same two areas.

    Yeah, this one has slight weakness in the eaves. I think the relief was too high in the design. You don't see this for 1967 and later dates.
