Some time in the 60’s because I have a silver quarter. It sounds tinny when you drop it. The quarter is from 1964. I have a dime from 1946, but I can’t tell if it is silver. My quarter rocks. -s

1964 was the last year for coins minted entirely of .999 silver, however, some coins were still minted with ,90 silver up until I think 1982 or so. If you can find a 1982 dime with no mint mark it is worth about $350 in any condition. That was the year that somewhere between 30,000 and 300,000 coins were minted at the S.F. Mint but the die for the mint mark wore off. Making the coins valuable for having this flaw. Of course the better the condition of the coin, the more it is worth. Now if only I could find an 1856 Flying Eagle penny in mint state 62 or better, then I would be in heaven.

1964 was the last year the U.S. stopped minting coins in solid silver. However, there was a series of coins that were sandwiched in silver and maybe an expert coin collector will come on here and cover all those coins and different years they were stamped. They all had different dates and percentages of silver but I am not enough of an expert in coins to know all that. However I am sure about the 1964 year for the solid coins.

CoinTrain has the best answer, but actually the U.S. still mints silver coins today. They are bullion coins and not for commercial use. They have a face value of one dollar and are made of 99.9%pure silver. They have been minted since 1987 and are called American Eagles. There are also special commemorative silver coins and silver proof coins. Check out the US Mint site below.

RE:
what year did the US stop minting coins in silver?

Although the US has never had circulating coins of pure, unalloyed silver, from the opening of the mint in Philadelphia in the late 1700s on up through 1964 we had coins that were mostly silver — alloyed with copper.

Here’s how it went:

Until 1837 the percentage of silver was 89.24% for silver dollars, halves, quarters, dimes, and half dimes.

From 1837 through 1964 the silver percentage was 90%.

From 1965 through 1970 half dollars and silver (Eisenhower) dollars were made with a core of 21% silver, clad with an outer layer made from 80% silver.

From 1971 through the present the US Mint has produced no coins for circulation that contain any silver.

coins prior to 1965 were minted using silver bullion, so your answer is 1964

I believe 1964 coins were the last.

They never have stopped. However, they don’t contain as much silver since 1964. Now I know this because I was there alive a well. Now I,m just alive and…and….well, I’ll let you know in the morning .
