Special plastics are often used to house antiques so any gas they may release does not harm the valuable contents, acid free paper is another for documents of historical value.
Would you happen to know what sort of cloth is safest for wrapping silver in? I had a small project to create a small bag of silver.
No idea offhand, though I would definitely stay away from anything that is dyed as the dye may tarnish the coins which I am guessing this is what happened to another poster in this thread with the velvet that tarnished his coins. The problem is no matter which material you use there are drawbacks, natural materials will eventually rot or go mouldy in a damp environment or may have been bleached, synthetic may release gasses like many plastics do.
