"Pure" silver coins were never minted in Britain. The closest to pure silver used in coins is sterling silver which is 92.5% silver usually alloyed with copper.
Sterling silver coins were last issued for general circulation in 1919 and 1920, beyond 1919/1920 the coins were debased to 50% silver.
The Royal Mint still produces Proof and bullion coins (not for general circulation) which are made from sterling silver, but this is reflected in the price you pay for them.
First, U.S. coins were never pure silver. The silver American Eagles come the closest at 99.9% pure. As for the circulating coins, they were 90% silver and were last dated 1964 even though mintage of the 1964 dates continued part way into 1965 to counteract hoarding.
"Lady of the Century" coins were minted by a large variety of countries, in a number of different years. The have been variously minted in 24 carat and 22 carat gold, pure silver, sterling silver and 50% silver.
Circulating U.S. coins were never made of pure silver, but all dimes, quarters, and half dollars minted before 1965 were 90% silver with 10% copper.
There can't be a pure silver 1965 dollar. No silver dollars were minted after 1935, and in any case pure silver is too soft for circulating coins. They all contained at least 10% copper.
> The famous "Mercury" design appears on dimes minted from 1916 to 1945, not dollars.> No circulating US coins were made of pure silver. It's too soft, so they were always part copper.Please post a new question with the coin's date and mint mark.
The reason silver coins minted for circulation weren't pure silver is because without an added metal, usually copper, the coin would be too soft and would wear out quickly.
The rising price of silver forced Canada to reduce, then eliminate silver from its coins in 1968. Those minted early in the year were made of 50% silver, 50% copper. Those minted later were made of pure nickel. Nickel is attracted to a magnet, so a 1968 coin that does not stick to a magnet must be an early half-silver coins.
The coin is 90% silver and 10% copper not pure silver. The date is very common and circulated coins have retail values of $3.00-$4.00
See other post The US never made circulating $1 coins from pure silver, it's far too soft so the metal was alloyed with 10% copper. The closest things to a pure silver "dollar" are the so-called Eagle coins minted since 1986 for sale to collectors and investors, but these aren't intended to circulate. Please determine the date on your coin and post a more specific question.
US silver dimes, since 1873, contain .07234 oz of pure silver. However, except for certain collector coins, there is no silver in dimes minted from 1965 to the present .
Nothing is 100% PURE silver but like most silver coins it is 99.999% silver
ALL coins are "minted" coins because they're made at a mint.They are never pure silver or gold. US silver coins used to be 90% silver with some 10% copper added to make them harder so they wouldn't wear out as quickly.Now coins like quarters or dimes are clad. That means they are like a sandwich. They have a layer of copper and nickel on the top and bottom, and copper in the middle. If you look at the side of a quarter, you can see the copper.
