1965 Silver Dime MS-66 But Graded Sp?

Also this is about the best pic I can come up with of the front clad.

Also from what I understand they plucked this coin straight off the line in 1965 and put it in a case. I'm just wondering if they were really busy that day and didn't realize what they did wrong cause there should be copper on the edge and I am a realist. I ignored my mother's please about this coin being real but three or four months later I'm actually paying attention to what she says. When I search the coin on the PCGS website they say this is a SPS or something like that?

Alright I will break it open soon but I'm gonna wait until I can break it in front of an authorized dealer so they can see if this is possibly real or not. Thank you for the heads up and what I need to do. I will post picks and a vid for the outcome. Thanks again.

Here is a pic of the obverse In different lighting

The only reason I am having a hard time deciding to break it open is because then it won't have it's mS66 rating. Or at least that's what PCGS says. Plus with it being rated already you would think they wouldn't miss a missing clad. But I really appreciate your help! This coin is so rare like I said I'm having a hard time getting anyone to even look at it lol. But if it was a real silver mS66 from 1965 it would be worth so much that wouldn't even want to sale it. Thanks again and I will post my outcome. It is very helpful being apart of a great coin community as I am always googling and reading things that just happen to pop up from the search and it's usually this forum 90% of the time.

Thank you! Ok well I have been trying to learn the difference between clad and silver dimes to see if I can tell any difference. I have a couple silver dimes in the 60's to compare it with but where it is mint and toning it is very hard to decide what it is or isn't. Plus it's in a PCGS case....
