Hi --
I like to collect used stamps. When I bought some from
ebay they had a musty, smoke smell (see previous post I made a couple of years back). The smell went away when I put them in Vario (plastic, no PVC!) sheets and then put the sheets in a box with silica gel.
So that makes me wonder though... how do I know stamps I buy are "safe?" Is it enough to just look under a magnifying glass and see that they have no visible spots? Should I buy a special lamp and use that - if so which one is recommended? And can you tell some tips on how to use it and what to look for?
I store my stamps in Vario sheets and those in a polypropylene box with silica gel and that keeps the humidity down well below 50% year round.
Thank you!
