Mister Tom,
I would start by looking at the price guides to see if any of these are potential keys or semi-keys within the series.
Without any practical grading experience there's not much you can do except trust in other experienced graders. This is particularly true in mint and proof sets ... they all look spectacular. PCGS graded gems (MS69-70 or PF70) command big $$$$. This is because only a very few of the millions minted pass their strict standards. And to avoid "gradeflation" they usually reserve these grades for submissions from their premier customers (my take, others may disagree).
I would first find a local coin dealer that you trust and request their opinion. This may prove difficult as most dealers these days consider modern Mint products "dreck". They may not be willing to expend the effort.
Posting pictures here is sometimes an option, but in your case you would need professional pics for us to determine if the coin is a gem.
Sorry to paint you into a corner here, but this is the reality of modern mint products.
