Silver Bullion and Coin Purchase

Scrap silver is harder to sell because the buyer has the determine the exact weight of silver in troy ounces. I like coins that already have the weight in troy ounces or grams stamped on them and that already say .999 or.9999 fine silver on them. I do not like silver bars, because most are made by private mints. I only buy government issued silver or gold coins. This is just my philosophy as a buyer of precious metals.
