Hopefully this can be something to look for, as I doubt the forgeries would use such a complicated process, and simply be spot-glued around the edge? Report this Post to the Staff
ericnh Valued Member United States 109 Posts	Posted 04/05/2008 2:56 pm The reason I asked is because a coin I just received looks like it was opened and then resealed by melting the plastic in a few spots around the edges. So I grabbed all of my NGC slabs to compare and low and behold all of them have some sort of "edge melting" or deformation. The problem, and the reason I asked, is that all of he coins were purchased from many various retailers and auction sites. So I have trouble believing all of them were tampered with so I was hoping that maybe it was part of the encapsulation process. Report this Post to the Staff
