No. If you're referring to proof coins 1968-present, no cent or nickels have any silver. Then with dimes, quarters, and half dollars, look at the edge of the coin. A copper/nickel clad proof coin will show a ring of copper, same as any P or D versions. A silver proof won't have that, and it will also be heavier. Meanwhile, all dimes, quarters, halves, and dollars before 1965 contain silver, for all mint marks.
Yes, all the silver war nickels have mint marks, even Philadelphia. There will be a large letter P, D, or S above Monticello.
The mint mark position on all Peace dollars is near the word ONE on the back. No mint mark = Philadelphia D = Denver S = San Francisco
Yes they are, all "S" Mint 1971 & 1972 Eisenhower dollars are 40% silver, but ONLY for those two years. In 1973 the Mint added copper-nickel clad "S" Mint coins along with the 40% "S" Mint silver coins
All are worth about $3.00 each just for the silver, some are worth a lot more but it depends on the date and mint marks
Only the years 1942-43-44-45 have 35% silver content. you can identify the coins by a large mint mark P-D-S on the back of the coin above the dome of Monticello. But not all of the 1942 coins are silver, a Denver mint and Philadelphia mint were struck in copper nickel and don't have the large reverse mint marks.
In WWII, The United States had to use 56% Copper, 35% Silver, and 9% Manganese. The dates for these 35% silver nickels are 1942(P,S) (NOT D), 1943(P,D,S), 1944(P,D,S), and 1945(P,D,S). The mint marks on these coins are located above the dome of Monticello. Contrary to popular misunderstanding, these are the only US nickels that ever contained silver. The rest are all made of an alloy of 25% nickel and 75% copper.
In general, "S" mint marks from the San Fransisco mint are more scarce than other mint marks when it comes to pennies. But just because it has an "S" on it doesn't make it a rare, or even scarce coin.
The "S" is the mint mark for the US Mint at San Francisco, California. All US Mint facilities place their own letter, which identifies them, on nearly all of the coins they mint. The larger than normal mint marks on the "war nickels" were placed there to indicate the coins were of a different alloy than previous nickels, containing 35% silver instead of nickel.
There are 3 possible mint marks - O, S, and CC. Please post a new question with the specific mark on your coin.
Need a date to go with the O a lot of coins have O mint marks...... 1888
No. Silver dollars minted at Philadelphia did not carry mint marks. Mint mark positions are: Seated Liberty dollars - under the eagle Morgan dollars - above the DO in DOLLAR Peace dollars - between the word ONE and the eagle's tail feathers. Mint mark letters are: blank = Philadelphia D = Denver S = San Francisco O = New Orleans CC = Carson City Dollars weren't minted every year at every mint, so there are many gaps in the series.
The mint mark position on all Morgan dollars is the same, above the DO in DOLLAR on the back. Possible mint marks for Morgans are: No mint mark = Philadelphia D = Denver (1921 only) S = San Francisco O = New Orleans CC = Carson City
