I would suggest that you join the International Society of Worldwide Stamp Collectors - http://www.iswsc.org - lots of exchange possibilities there.

go to USPS.com and look at the stamps to find out the value of that stamp. You can still use it you will just have to add more if its not enough.

The best to place to get an accurate value for a trading card is on eBay.  Millions of people participate and will usually give you an accurate idea of an item's value.  Otherwise, you can check on Beckett.com by opening a personal account and adding the cards(s) to your collection - it will show you the total value of the cards you select.  Good luck!!!

Heritage numismatics has an online collection tool.  You have to register on the site, but it is free.  If you buy from them, then the coins you buy can be automatically added to your collection list.  In addition to listing the coins and grades, it also gives current wholesale value for each coin.  Just go to MyHeritage on the following web site.  Good luck!

1) Go to a library with a good periodical collection and look at old advertisements.\n\n2) Or research the historical rates of inflation and work backward from todays prices.\n\n3) Go to nearby "adult" community and ask for the oldest person with the best memory.\n\nDont ask my grandfather..according to him everything only cost a nickel.

One of the sites I regularly check out is Beatles4Me, they seem authoritative enough with pricing of records and memorabilia.\n\nThe Beatles Collectibles site does not have a whole lot of vinyl information but fairly good information on memorabilia.

Go to your local antique store or an appraiser.  They have methods of finding out where an item was made, how old it is, etc. often with their services for free.  Hope this helps.

There is a site for collectors of currency listed below. I suggest you start there, and post your question to them, since Yahoo seems unlikely to be helpful in the answer here.

Depending on the true rarity of your collection, a large auction house might me interested.  Sotheby's for example.\n\nIf your collection is not THAT rare, try the smaller StampAuctionNetwork where you can list your collection personally.

Best way to find the value of anything is to check eBay. eBay will tell you what people will actually pay you for an item as opposed to what you can expect to pay in a dealer's shop.
