oriole Pillar of the Community Canada 5238 Posts	Posted 02/21/2025 5:59 pm I'm replacing some missing felts in an old coin cabinet, and I could only locate polyester felt, not wool felt that presumably was used. Does anyone have any knowledge of the effect of polyester on coins? Report this Post to the Staff

HondoB Bedrock of the Community United States 24878 Posts	Posted 02/21/2025 6:46 pm I believe that polyester is inert. There are quite a few types of coin flips made with it. However, you have to be sure that there are no other chemicals added to the polyester which could affect your coins in the long term.

HondoB Bedrock of the Community United States 24878 Posts	Posted 02/21/2025 8:06 pm I would first try to find a compatible wool felt online. A cursory search yielded quite a few options. Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff
Spence Moderator United States 34393 Posts	Posted 02/21/2025 8:11 pm @ori, I seem to recall there being a big discussion of glue outgassing in a prior CCF thread about coin cabinet liners.

HondoB Bedrock of the Community United States 24878 Posts	Posted 02/22/2025 02:08 am Quote: might there be chemicals in the wool felt as well? Perhaps. But you could probably find some organic chemical-free wool. If it's dyed, it has some chemicals in it. Wash it well - put it in a garment bag (pillowcase) in the wash so that it doesn't disintegrate.

HondoB Bedrock of the Community United States 24878 Posts	Posted 02/22/2025 6:03 pm I see that there are organic wool felts colored with natural dyes. I wouldn't skimp on something my coins contact for long periods of time. Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff
