No, the US mint has never minted a 2 inch silver coin for circulation or for bullion purposes. The largest silver coin in diameter that I know of that was produced by the US mint would be the American Silver Eagle with a diameter of about 1.58 inches and the US silver dollars which have a diameter of 1.5 inches.
If such a coin exists, it was made by some private company and NOT the U.S. Mint. No coins ever made for circulation were pure silver, and the last year for genuine Morgans was 1921.
The value of a silver coin is always changing because the value of silver is always changing. See the related link below for a silver coin value calculator. This does not give the actual value of the coin but it does give the value of the metal used to make the coin. This is know as the melt value.
Just the year does not make a coin rare.
yes, dental silver is mixed with something to make it harder.
The US never made silver pennies. It would cost too much for the mint to make them. Your coin is plated silver this adds no value to the coin.
The U.S. did not make any $20 silver coins, look at the coin again and post new question.
The vast majority of 1992 quarters are not silver and are the standard copper-nickel composition. If your coin was not found in a silver proof mint set, most likely it is not silver but rather copper-nickel. If your coin was found in a silver mint proof set, leave it in its packaging and do not remove it. However, if you think that your coin is silver, there are a few tests to see if it really is silver. First off, your coin should have an "S" mintmark on the right side of George Washington's head by his ponytail. If your coin lacks this, it is not silver. However, even if your coin has an "S" mintmark doesn't make it silver, your coin could still be a copper-nickel proof. What you need to do then is look at the edge of your coin by the reeding. A copper-nickel coin will have a line of brownish red copper through it, a silver coin will not and a silver coin will appear 100% white. If there even is just a little bit of copper showing, it is copper-nickel and not silver. However, if your coin is one of the silver proofs, it is worth about $5.25 for the silver content and perhaps as much as $6 or 7 if still in mint-state condition.
Silver had become far too expensive to make general circulation coins from and a cheaper method was to use an alloy of copper and nickel. This was an international trend during the mid to late 20th century. The last ever Australian circulating coin to contain any silver was the round 1966 50 cent coin which had a silver content of 80%. This coin was withdrawn in 1967 due to the sky rocketing price of silver. From 1946 to 1964, all Australian predecimal "silver" coins had a 50% silver content. From 1910 to 1945, all Australian predecimal "silver" coins had a 92.5% silver content.
It depends on the metal used to make it, a coin made out of copper, nickel, lead or other cheap metals might be worth a few cents, however, the coin could be worth its value in silver if it was created in that and 90% silver it could be worth around $20 in silver.
If you got the coin in change, it is not made from silver. No country could afford to make general circulation coins from precious metals.
Not that I know of, and I couldn't find anything about one on the internet. Make sure it is King Arthur.
no to soft to make coins out of solid silver . .999% is the most silver in any coin .
