From the first New Zealand coins issued in 1933, "silver" coins had a silver content of 50% until 1946. From 1947 onwards, all New Zealand "silver" coins were made from a copper-nickel alloy.
Zero. No general circulation New Zealand decimal coin has any silver content, or any other precious metal. Prior to 1947, New Zealand predecimal silver coins had a 50% silver content. All "silver" coins minted from 1947 onwards were made from a copper-nickel alloy. The only exception to this was the 1949 Crown (Five Shillings) which was minted from 50% silver.
All New Zealand "silver" coins from 1933 to 1946 inclusive had a 50% silver content. All New Zealand "silver" coins from 1947 onwards, were made from a copper/nickel alloy.
Yes they do. No British decimal general circulation coin has any silver content at all. The "silver" coins of all Commonwealth countries similarly have no silver content.
Zero. No New Zealand general circulation coin has had any silver content since 1946. The only exception to this is the 1949 and 1953 Crown (Five Shilling) coins. From 1947 to 2006, all New Zealand general circulation "silver" coins were made from a copper-nickel alloy. From 2006 onwards, all New Zealand general circulation "silver" coins were made from nickel plated steel.
No. No New Zealand general circulation coin has contained silver or any other precious metal from 1947 to present day. Prior to 1947, New Zealand "silver" coins had a 50% silver content.
Yes. All New Zealand "silver" coins minted from 1933 to 1946 inclusive had a 50% silver content. From 1947 onwards, they were all made from a copper-nickel alloy.

No general circulation New Zealand decimal coin contains any silver. New Zealand 50 cent coins were made from a copper nickel alloy from 1967 until 2006.
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 The last of these coins were minted in 1963 and 1964 and were withdrawn soon after decimalisation in February 1966.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was a terrible blunder since the silver content of the coin was worth much more than 50 cents, and these coins were withdrawn very quickly.
Coins struck for circulation in the US today have no silver in them.
There have been six King Georges from 1714 to 1952. 1919 and 1920 were the two years when the British silver coinage was debased from 0.9250 to 0.5000 silver. Which year the change was made depends on the denomination of the coin. Prior to 1919/1920, all British "silver" coins had a 92.5% silver content. From 1919/1920 to 1946, all British "silver" coins had a 50% silver content. From 1947 to present, all circulating British "silver" coins had a 0% silver content.
No circulating British decimal coin contains any silver at all. The closest you might have got, prior to 1920, to a pure silver circulating coin was 92.5% (sterling silver), the standard at the time. From 1919/1920, the silver content of British coins was reduced from 92.5% to 50%. From 1947, all British "silver" coins contained no silver at all, they were made from a copper-nickel alloy. There are a number of non-circulating British coins minted from time to time, that have a 92.5% silver content.
