The value is about .99 cents - $2.00 depending on what little letter is stamped on the coin is it a P or D or S.\nAnd what coloration does it have look at the site below for a list of values (this guy seems to be selling them though so you should check Ebay to see what they're going for).\nI didn't see the other guys answer checking with his site would probable be best.

you could either take it to a card store and ask them, or even look it up in a becket magazine or look up becket prices online.

I think the best thing to do would be to search for one on eBay and see how much they're asking.  If that doesn't work or if you don't like what you see, take it to a local antiques dealer and see what they think.  I know it's not really old enough to be antique, but I've heard antique dealers are appraising toys from the 80's now, so why not?

If it's a real misprint and not a fake. It will be valued high for collectors.

You did not really give enough information for me to tell you for sure about what the stamp might be worth.  Scott 632 1c green with the picture of Franklin facing left in a oval with the words United States Postage around the outside of the oval with perfs 11x 10 1/2  was first issued on June 10, 1927.  In mint or used $0.15 in very fine condition.  Scott 552 of the same design but perf 11 x 11 first issued on Jan. 17, 1923 in mint condition $1.40 mint never hinged $2.50.  Used $0.15.

I would check the closed auctions at Ebay.com or Yahoo auctions. Those are usaully good indicators of what the current value is on these types of items.

I would look on E-Bay under "vintage magazines" or something like that and see if anyone else has same type up for auction.  See what their opening price is and if anyone has bid on it.  That would help.  It would also tell you if there is an interest in the particular magazines you have.  I've been selling some antique crystal on there and sometimes there is just no market for some of it, though, it could change in a week.
