I suggest using Lighthouse or Harberger. Both are plasticizer-free, which is a MUST for coin collectors.
The problem here is your mentioning a seller not necessarily a manufacturer. To really know what you are buying, it should be so stated on a package. I too buy at coin shows in bulk and have no idea where they come from or what they are made from. The Whitman
web site says Mylar but does not stipulate the cardboard material at all. If you go to Harris, your sent back to Whitman
since those are the same c ompany. To make sure of what you have or want, always find out where made, of what, and by whom.
