The short answer is 1966.
Australias last "silver" predecimal coins contained 50% silver. The last of these coins were minted in 1963 and 1964 and were withdrawn soon after decimalisation in February 1966.
The only Australian decimal general circulation to ever contain silver, was the 1966 (round) 50 cent coin which had an 80% silver content.
Due to the soaring price of silver a short time later, and with the benefit of the wisdom of hindsight, this was a terrible blunder since the silver content of the coin was worth much more than 50 cents, and these coins were withdrawn very quickly.
Prior to Decimal Currency being introduced in 1966, all Australian silver coins had at least a 50% silver content. After the introduction of Decimal Currency, the only general circulation coin to have any silver at all was the 1966 Fifty cent coin which had an 80% silver content. Due to the increasing price of silver, the next Fifty cent coin to be minted in 1969, was the same as all other silver coins, 75% copper and 25% nickel.
The last year for 90% silver dimes, quarters, and, half dollars was 1964. Half dollars were then made with 40% silver until 1970.

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.
The last year for silver dimes and quarters, as well as 90% half dollars was 1964. Halves 1965-70 were then 40% silver. All dimes and quarters 1965-present and half dollars 1971-present are copper and nickel.
The last 90% silver half's made for general circulation were in 1964. 40% silver coins were issued until 1970.
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.
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.
The last year for the Canadian silver 5-cent piece was 1921, except those coins weren't called nickels because they didn't contain any nickel. The Canadian nickel (actually made of nickel) was then introduced in 1922.
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.
