Where To Get Information?

I just came across a box of sheets and part sheets of Easter Seals, Christmas Seals, Boys Town, and National Wildlife Conservation Cinderellas. The sheets go back to the 1930's. I think most are from the US, but some might be Australia or Canada (judging from some markings on the folders they are in). Is there an online catalog of these somewhere I can see what I have? Are any rare? I noticed some different varieties, especially among the national wildlife sheets have multiple different varieties for a single year (I see at least 3 different ones with a 1979 date, although the stamps appear the same, the sheet configuration is different).

adcaplan, go to http://kozersky.com for an answer to all your questions! There are several other dealers who specialize in these stamps. You might also try E-bay.

First and Foremost go directly to http://www.seal-society.org/.
and read everything carefully.
That is the very best place to start.

With virtually no exceptions, seals from the 1930's on are not rare. Even stacks of sheets of them sell for very modest amounts. Collectable, but no cash value.
