Hi, I have a stamp 2 cent from 1898 in the colour of brown. My catalogue only lists it in red and green. Can you help me to identify it? Thanks in advance :-)

This stamp is destroyed because it was stored in a wrong kind of stamp album.

The Collector's Club of Chicago paid for an extensive scientific study of different plastic materials several years ago. Storage in PVC was absolutely proven to be detrimental.

You might want to search for Collector's Club of Chicago if you would like to read their reports which were made available to the public.

Roman is absolutely correct, stay away from PVC material.

HI archiem,

that's very interesting information! Do you have any download link for me about the PVC research?

Kind Regards,

Roman

It has been some time since I read these reports, but the Collector's Club website is located at https://www.collectorsclubchicago.org. They have links to their publications and reports at the top.

Leonard Hartman is in change of their publications. He can be reached at Leonard@pbbooks.net.

If I remember right, the Arthur Salm Foundation was responsible for underwriting the cost of the reports.

Hope this helps.

I would assume that there is a certain amount of research on this subject in the Library and Museum industries also.
