It was 1964 when the last coins in the US were made from 90% silver.
1964 was the last year for 90% silver coins and 1970 was the last for 40% silver coins. Special Bicentennial (1776-1976) collectors coins were made in 40% silver. From 1992 to date proof collectors coins have been struck in 90% silver.
No. find the website for Calgary Coins. There they will tell you the metal content and a VERY brief history of Canadian coins. 1968 was the last year silver coins were minted for circulation, and then only for part of the year and in debased .500 fine alloy.
1837 was the year US silver coins changed to .900 silver & .100 copper, that caused a slight reduction of silver.
Yes, unless the coin is a very rare year or mint.

1964 was the last year for any 90% silver coins struck for general circulation.
Yes, but 1964 was the last year for circulating 90% coins.
Sometimes a coin is so worn that you can't read the date. These coins are called junk, but if it is silver, it is still worth the silver weight.
Never. The US has never made a solid silver coin. They have made coins with mostly silver but they always contain other metals too.
The government stopped putting solid silver coins out in the late 60's. Any 50 cent piece past 1969 will not be silver.
The series of Eisenhower dollars is a little confusing. Special 40% silver collectors coins were produced from 1971 to 1976. No 1977 or 1978 coins were struck in silver. None of the coins made for and released into circulation contain any silver.
