Cuts Like a Knife - Part 1

Lately, there have been a lot of conversations about sports card scams.  Some scams involve counterfeits.  Others involve shill bidding.  Then there is pack searching and resealing.  No doubt, all of these things happen.  By association, it can give many the impression that all collectors are dirtbags.  I know that not to be true.  Hang in there good guys.  But, there is another scammer activity that has me interested, card trimming.  In my opinion, it could be the single hardest scam to detect.  To compound matters, it arguably presents the largest potential financial gain to the scammer as well.
