IME, coins and "used" jewelry often can be sold only for scrap value. In other words, they will be melted down unless there is some perceived value due to coinage date, mintmark and other rarity.

I helped liquidate an intestate estate and the the gentleman had a carload of real silver coins. None were rare, all were melted into ingots. Jewelry had the stones removed and the setting also got the torch.
