It has some nice details and as mentioned some corrosion. Also a couple of rim dings. Looks like an S-70.
It is an S-70. Has nice detail, color is off, some corrosion, I wonder if that area at 10:00 could be a planchet defect? I wonder because the 13th coin in the Condition Census is described as "XF-40 with obv planchet defects and weak striking at NITE". It is the only piece listed in the CC with weak striking at NITE. Unfortunately I don't have a picture of the CC 13 coin to compare it to.
