I found a collection of MINT Polish stamps. Where can I sell them for the most money?

Recently, I visited my mother to help her clean out her basement. Along the way we found a book full of stamps from Poland (none have ever been used) spanning from the late 50's to the late 70's. These include whole sheets of communist era stamps and olympic stamps and so on. She was going to throw them out but I thought they may be worth something. Where do I turn?

Wow. If I had any money I might want to buy them. Don't sell them to a dealer, you'll get a real low price (they need to make a profit). Selling them to a collector is best (if they have the money). EBay, or join an online stamp club. Yahoo has stamp clubs.
Reply:Look for coin dealers/collectors in your city. They usually deal in stamps also. Do some research on your stamps so you will have some idea what they are worth.
Reply:ebay always has the best deals... so try on there because you will get more interested people from around the globe not just in your town, city, or even state.
Reply:Post your items on EBAY,Fix a Reserve price of ,say,10,000 dollars.Let the auction go %26amp; see how the bidding goes.If the reserve is not met, there's no sale.It's a way to get an idea what it's worth to someone
