I have been given collectables for several years and I have no idea how to find the value of my items, such as a Beatles phone card (never used), Mighty Marvel Holiday Heroes Telephone Greeting Card (expired 12/31/95. I own approx. 100 baseball, phone, hockey, and football cards.

Okay so here's an idea . Go to eBay and look up all your stuff. There is a least one of everything on that site.See what there stuff is going for just to get an idea. If that doesn't satisfy you ask around the different stores in the area you live

The sports cards, you can go to a library and get a book, or books, on collectibles in sports memorabilia, or any other collectible item you may want to find.

If you want a true price for your items I would suggest going to either eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices (http://www.ebay.com) or a site like that. Also for the individual items such as sports cards I would suggest places like Sports Card Forums (http://www.sportscardfreaks.com) because they are good ways of finding true market values

The value of your collection - Ebay will give you what others are willing to spend - and they want the best deal, of course. Yes, you get a very good idea of what the buyer's market is like. But for value - if you want to insure those collections - I still go for a resource like those found in your library. That can tell you an appraisal value. If you can find a local antique card dealer, ask for an appraisal. There is a website for "Antiques Roadshow" where you can submit questions. Antiques Roadshow Online | PBS (http://www.pbs.org/wgbh/pages/roadshow/)

Good luck to you.

That is 100% incorrect. Appraisers have little to no knowledge about sports cards. All they do is read one of the publications such as Beckett Magazine or Tuff stuff. They do not have the ability to judge whether a card is authentic and the majority of these prices are so far from actual prices that you will be grossly disappointed when you try to sale these cards. Cards should not be classified as Antiques because they are actually collectibles.
