1960 Penny Graded At MS-64?

hello forum friends, yesterday I currently picked up a few coins from a dealer at a flea market (he is a very smart man with very strong knowledge) and a couple booths down there was an uneducated man selling a few things (got a 1954 2$ Canadian, 1974 2$ American, 5 x 1967 1$ and a 5$ 1954 Canadian all uncirculated for 20$ (amazing considering the 5$ is worth double that) any how, he through in this graded coin, its graded by PPGS, quick glance I assumed it was PCGS so I agreed to take it, it was free after all, so once I got home I realized, hey, this isn't PCGS its PPGS, and the grading didn't seem right.

the coin is very sharp, very red, spectacular condition, but it has some red spots on it, maybe corrosion,i did remove this coin from the false grader sleeve (it was cheap and the paper with the grading was hand cut with scissors anyways) and I put it in a 2X2, but now that I'm looking at it, I think its pretty close to that grade, I tried to get the best pictures I can!

HELP!
