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.
Quarters and most other silver US coins contained 10% copper; the last coins made of that alloy were dated 1964. The US has never made solid silver circulating coins. Pure silver is far too soft for use in coins, so it was always alloyed with copper for hardness.

1964 is the first year of issue and the only year it was struck in 90% silver. The coins are very common. Even uncirculated coins are valued only for the silver they contain, about $12.00.

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.
