10 Troy Ounces of Silver is worth around $100 - $120. It depends on the condition of the silver (e.g. is it in a rough cast bar, jewellery or a bullion coin) and who you sell it to (e.g. coin dealer, jeweller, and pawn shop). These ten ounce silver bars measure about 1 5/8 inches wide by 2 7/8 inches tall and they are almost 1/2 inch thick.
