Message:: [QUOTE="GDJMSP, post: 1554975, member: 112"]A couple of questions for you clad. You've claimed before that some of the mint packaging had PVC layers. But that is contrary to everything I have ever read, heard, or experienced. I was a Mint and Proof set collector for 40 years, and never once did I ever see any evidence of PVC being used in the packaging. So my question, have you ever had the plastic analyzed ? Yes, the packaging was made of layers, but it was made of layers of pliofilm, a material made from rubber. And that material needs no PVC for it to be or to remain flexible. Which is what the PVC compounds are  used for. Second question, you mentioned Mint Set coins being washed after striking. Again that is something that I have never heard of. I am aware that the planchets for Mint Set coins go through a special washing process, but only the planchets. Nothing is done to coins after striking, and never has been. The one exception would be the Sacky coins. Those coins were burnished (and burnished is just another word for polished) after striking, and those coins were sprayed with a special coating to retard toning and discoloration, after they were burnished. But other than that I am not aware of any coin in any Mint Set that has ever had anything done to it after it was struck. So my question - what leads you to think otherwise ?[/QUOTE]
