This isn't really a
TPG question, it's a
TPG slab question. I couldn't figure anywhere else to put it. (Help, Moderator?)
I have several
TPG slabs with scratches, or worse, scuffs. I only notice the ones over the coin, but some scuffs obscure or distort features.
I have never understood how they got that way. Based on accidentally knocking a few on a hard floor 3 feet below, the slabs seem hard as nails. I have never actually damaged one. Unfortunately, many prior owners of my slabbed coins have not had the same good experience.
I was just reading an article on coin photography in Penny-Wise, the journal of the Early American Coppers society. It recommended using Slab-Renew to repair damage and yield better pictures.
I haven't previously heard of this product, but if it works I've got plenty of places to use it.
Any comments on this product? I don't want to make things worse. I am very bad with my hands and would not want a product that is difficult to use.
Thanks!
