Scrap Sterling silver sells very fast on eBay. I usually price it at 85% of the current melt value. Just be sure to break down candlesticks and other weighted items. You'll do much better if you remove any cement or metal rods in them. No one wants to buy weighted items, unless they're priced really cheap.
Gold rings are even easier to sell. I price them at 90% of melt and they usually sell the first day I list them. I've also sold oxen shoes, 1930's shotgun shells, boy scout neckerchief slides and many other items that I've dug up over the years. People will buy almost anything on eBay!
