90% US Silver Coins

Junk silver refer to silver coins that contain no collectible or numismatic value beyond their silver content; junk coins are bought and sold primarily for their silver value.  The price of these coins is determined by multiplying the silver weight of the coins by the current spot or market price of silver. 90% of junk silver are U.S. silver dimes, quarters, half dollars and dollars minted in 1964 or earlier. They can also refer to 40% silver Kennedy half dollars (minted from 1965 - 1970), 35% silver war nickels (minted from 1942 - 1945), or even foreign coins, such as 80% silver Canadian dimes, quarters, half dollars, and silver dollars minted in 1967 and earlier. Since 1965, the US mint stopped using silver to mint coins for general circulation (except the 40% silver Kennedy half dollars). Listed below are examples:

Coins for junk silver are often traded in bulk (junk silver bags, rolls or stacks). Since there's a nominal premium placed on these silver bullion coins, they can easily be bought by collectors and investors alike. Investors buy these coins to protect their assets from inflation, subsequently during economic uncertainty, and likewise for profit if they believe that the price of silver will increase.
