I've tried listing on eBay, each stamp and realized that it's very difficult to price and valuate your stamp collection unless you've really spent a lot of time learning all the variables. My advice on how to answer the question "Are my stamps worth anything?" Take it to a stamp collector who know's his stuff. That really is the best way, but that being said it does take some time and they may charge a fee, or charge a fee and then offer to purchase your collection and absorb the fee.
