A friend of mine does estate clean outs, and she said that they often find dental scrap in houses when they are cleaning. She said that depending upon the size (one to four grams) and the quality of the metal (10k to 22k gold or alloy) they can range from $40 to $100. It depends on the going price for gold too. If it is just sitting in a drawer, and you aren't using it why not sell it? You would be surprised at how many people sell them. My friend told me that at first she felt weird bringing them to the jewelry exchange but the guy told her that he gets people in there all the time. He said that as people get dental work replaced, they have no use for the old stuff, so they turn it in for a little money.
