There’s a lot of factors, such as where you sell and the specific state of the silver. Raw silver ore is about 5 gp per pound, as there still needs to be some processing done. A trade bar of silver aka one that can be immediately proceed into stuff is worth 10GP per pound. But raw scrap silver, which has already been proceed but isn’t in any notable shape or form, is 5 GP per pound.

Obviously if sold as finished products, such as holy symbols and such, their value is much higher. A silver necklace can go for much higher than a silver bar depending on the quality of the craftsmanship, even if that neckless weights 1/100 in silver compared to the bar.
