It's hard to see by the pictures but this 20-S is definitely convex on the obverse and concave on the reverse. It doesn't lie flat on the obverse side. Both sides seem to be the same consistency around the rim of the coin. It doesn't look like someone took a hammer to it. But it could still somehow be PMD.
