From 1965 to date all half dollars, quarters and dimes are sandwich coins, dollar coins from 1971 to date are also sandwich coins.

What is added to make coins minted coins?

ALL coins are "minted" coins because they're made at a mint.They are never pure silver or gold. US silver coins used to be 90% silver with some 10% copper added to make them harder so they wouldn't wear out as quickly.Now coins like quarters or dimes are clad. That means they are like a sandwich. They have a layer of copper and nickel on the top and bottom, and copper in the middle. If you look at the side of a quarter, you can see the copper.
