I recently bought my FIRST graded coin, a 1986 gold eagle certified as MS 69 by NGC. There is a very obvious spot of discoloration on the obverse, near Lady Liberty's torch. Looking up the cert on NGC's website shows it was there when they graded it. It's definitely on the coin, and it looks more obvious in person than it does in this picture. Doesn't really look like a copper spot to me, but maybe it is? Anyway can someone tell me if this is normal for an MS 69 or if this coin was perhaps overgraded? I'm curious for future reference, I wasn't expecting such a glaring flaw in an MS 69 coin...also wondering if I should return this coin. Thanks in advance for any advice!
