To check the value of an item on What's It Worth, enter the name of the item you wish to valuate in the search engine, and click Search. Click on the results displayed beneath the search bar to reveal prices that people have paid for the item.

Many of the search results lead to various eBay and other live auction sites where you can view what other people have paid for your object or for an object similar to it.
Some of the price results on What's It Worth vary greatly due to variations in the actual listed item. Check several results, and compare your item to the one that most closely matches your own to get the most accurate appraisal of your item.
