Oh, dude, they stopped putting silver in Mexican coins in 1979. It's like they were all, "Nah, we're done with the shiny stuff," and switched to cheaper materials. So, if you're looking for some silver in your money, you might need a time machine.
1937
The world wide increase in silver prices was the main reason.
i don't know maybe they hate silver. lol
The value of silver rose so the US had to use other metals to make coins. If our coins were still made of silver dimes would be worth $2 and quarters would be worth $5.
They used 92.5% silver till 1920 They used 50% silver till 1947
Inflation caused the silver content of coins to be worth more than their face value so the US mint stopped making silver coins for circulation.
1964 all us coins stopped being produced with silver.
None of the Eisenhower dollars (1971-1978) that were released into circulation had any silver! Only special collectors coins sold directly from the US Mint were made from 40% silver and all of them have S mintmarks. None of the Philadelphia or Denver minted coins contain silver. The 40% silver coins were struck only from 1971 to 1976.
Silver is a precious metal, and just like gold, it's going to be expensive so they stoped using it because they realized that people could melt the coins down and have a ton of money in silver.
The last year for silver silver dollars was 1935. There were no dollar coins minted again until 1971, by which time silver coinage had been replaced with copper and nickel.
The last year for 90% silver dimes, quarters, and, half dollars was 1964. Half dollars were then made with 40% silver until 1970.
The last 90% silver half's made for general circulation were in 1964. 40% silver coins were issued until 1970.
