But I feel that "worth" and "price" don't always reflect each other, unless your able to find the right buyer. If you consider an opposite analogy, such as a retail jewelry store... The intrinsic "worth" of a piece of jewelry is rarely reflected in the price you would have to pay.

The only way you can ensure getting full value for an item is to hold it until a specific price is met and hope you can find a buyer. I don't think ebay is a great place to sell if that's the intent. This auction is a good example
