Actually you are better off with pre-1965 90% dimes and quarters. Today silver dollars carry a significant numismatic premium and half-dollars do as well to a lesser extent that will disappear in a crisis. Aldo there are exceptionally well made fake Morgans flooding in from China that fool even experienced dealers. I keep mostly dimes. At $500/troy oz. AG the melt value of a dime is $36.17
My vicious dog Fergus guards them for me.
