Is There A Problem W/ Counterfeits In Commemoratives?

Unfortunately, some of my collection focus has been affected by the thought of the existence of counterfeits. I would be afraid to buy a Trade dollar or some of the pricier type coins or key dates in fear that I will be ripped off.

I find myself drawn to finishing a collection in silver Roosevelt's and franklin's because I don't think the east would waste time making counterfeits of these.

So now, for the same reasons above I find myself starting to pick up a few modern commemorative in mint packaging, because I think these are safe, until today. I search on ebay I find this listing from Korea selling a set of 4 "Young Collectors series" Atlanta Olympics clad halves with a starting bid of $0.99. It may be a legitimate listing for an original mint product, but how can you really tell? Do the commemorative issues have the same problem with counterfeits as the classics? How do I know that the east is not creating counterfeit mint packaging, if they are doing the same with TPG slabs?

Just wondering. I hate being paranoid, but in this world it seems you can't trust anyone.

Here is the listing in question:
