@johnmilton was the first to bring up an MS grade. A few others nailed it. I was shocked to see PCGS give it MS-62. I bought it from a dealer years ago for $20.
But who was the very first to commit to not only MS grade but exactly MS62? Oh that's right, it was masterswimmer
AU55... the only sign of wear is the reverse on the diamond and it still has the edges on the C (which is the 1st thing to go).
