For those who are hodling... Came across this link to a museum conservation guide for looking after silver https://mgnsw.org.au/sector/resources/online-resources/collection-care/looking-after-silver/ Enjoy
I noticed the comment: "Protein based materials such as wool, felt, silk and leather also contain sulphur compounds that are harmful to silver." I wonder if mints (RAM, RM etc) who do/did package collector coins in these materials are aware of this potential problem.
