What is the value of 1930s silver coins?

That's an extremely broad question! The U.S. struck 4 denominations of silver coins at 3 different mints during the 1930s. That give about 80 different combinations to choose from, allowing for years when certain coins weren't struck. But then you also have to factor in the coins' conditions which creates hundreds of possible choices.

Your best bet would be to organize the coins by dates and mint marks, then look at a site such as the one linked below to get a rough idea of current retail prices.
