Thanks for the pics!
The 1983 quarter is definitely
PMD and not a clip. On the reverse, you see the rim pushed in toward the center of the coin. On a true clip, the rim would be missing in that area as there was no metal there to create it. I hope that makes sense.
As far as the unopened rolls, open them! Unless you have Mint-wrapped rolls, you cannot be certain of what they contain. Yeah, they may be
mostly 2018s, but with a few stragglers that got into the mix. Look for errors/varieties on the 2018s and, of course, silver.
