There are many different man on moon coins that have been produced by many different countries and companies -- some are silver -- most are not. More information is need to determine if yours is silver.
Silver and gold were the materials of the first coins produced - they have been used as such for several thousand years.
Britain has produced silver coins for well over a millennium dating back to about 600 AD. The silver coins produced back then, were very similar to the Roman coins used previously. From 1947 onwards, no general circulation British coin contains any silver or other precious metal at all.
Just recently with the advent of bullion coins such as the American Silver Eagle. Coins intended for circulation were never 100% silver because silver is simply too soft of a metal for coinage. They were 90% silver in American coins until 1964 for dimes, quarters and half dollars, but other than bullion coins, no coins are made of 100% silver.
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.
The silver eagle coin has been the only US coin struck in pure silver. All other US silver coins were produced with an alloy of silver. Dollars, halves, quarters and dimes were produced with 90% silver prior to 1964. Halves were struck in 40% silver from 1965-1970.
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.
There were no dollar coins produced in the United States in 1906.
King Croesus of Lydia (c. 560-546 BC) produced gold and silver coins. After that point they were produced by many cultures including the romans, Greeks and Alexander the Great.also queen braxton made gold and silver coins (660-646b.c)
Until the end of WW1, many countries minted silver coins with a high silver content, usually 90% or more. In 1919/20, there was a sharp increase in the price of silver and many countries reduced the silver content of some or all of their coins to around 50%. At the end of WW2 when many countries were repaying war loans or, had had their economies destroyed by the war, the silver content was reduced further, or eliminated altogether. By the second half of the 20th century, most "silver" coins were made from a copper/nickel alloy. These days, only non-circulating investment coins or high value coins are made from silver.
The U.S. produced 20-cent coins from 1875-1878.The only U.S. coins dated 1965 that contain silver are half dollars.
Coins are not usually silver these days. Since the 1960s they have been made of copper and nickel. Silver coins from before 1965 in the US were 90% silver. Foreign countries have used anything from 40% to 92.5% silver in their coins, but to my knowledge, no one has used pure (100%) silver in currency.
