No they don't, not until 1906
No mint mark coins are produced at the Philadelphia,PA
The U.S. does not have any "F" mintmarks. Only P-D-S & W for any coins.
The San Francisco mint opened in 1854 and produced coins almost every year to the present except for a short time from 1955 to 1967. The facility at West Point began striking Lincoln Cents in 1974 and continued until 1986, but no mint mark was place on any of the coins. In 1983 the "W" mint mark appeared on gold commemorative coins. In 1986 American Gold Eagle coin were produced but did not bear a mint mark. Today the "W" mint mark appears on all gold commemorative coins and a few silver coins as well.
Philadelphia did not mark the Dime, Quarter or Kennedy Half dollar that year. Prior to 1980, Philadelphia did not use the P mint mark on any coins, with the following exceptions: > 1979 $1 coins > wartime nickels made from mid-1942 to 1945
Yes, there are instances of 1978 Jefferson nickels without a mint mark. This is due to a mint error where the nickel was struck without the mint mark. These error coins can sometimes be valuable to collectors.
No. In fact, huge numbers of older US coins don't have mint marks. For almost 180 years the Philadelphia mint didn't put a mint mark on any coins struck there. The only exceptions were the "war nickels" made from 1942 to 1945. Starting in 1979, a "P" mint mark was added to $1 coins, and the next year it appeared on all other denominations except the cent. Cents minted at Philadelphia still don't have mint marks.
As with all U.S. coins you have to know where the mint mark is located. Assuming you have only Washington quarters, coins dated 1932 to 1964 have the mint mark on the back, under the bow in the wreath. At that time Philadelphia did not use a mint mark so you'll only see a D for Denver or an S for San Francisco. Blank means Philly. Coins from 1965 to 1967 did not have any mint marks. Starting in 1968, coins from Denver have the mint mark on the front next to the bow in Washington's wig. Philadelphia coins are still blank. Starting in 1980, coins from Philadelphia have a P mint mark. If you want to find out where mint marks are on other types and dates, the site www.coinfacts.com lists locations on all U.S coins since 1838 when the first mint marks were used.
No error coins of that nature are known. Also, starting in 2009 the mint mark appears on the coins' edge instead of on the front.
To set things straight, it's called a mint mark. In general, mint marks were on the reverse side of older gold coins but not always. Also, coins struck at Philadelphia did not carry any mint mark in those days, so a coin without a mint mark is perfectly OK.I'd suggest looking at the site www.coinfacts.com. They have every date and mint mark listed, along with a description (and often a picture, too) of the mint mark location.
Nowhere. No U.S. coins dated 1965, '66, or '67 have any mint marks.
The 1928 Saint-Gaudens double eagle was only struck at the Philadelphia Mint so no coins bear a mint mark. But for coins of this series that do have mint marks it's just above the date. All so the 1928 double eagle is the highest mintage (8,816,000) of any US gold coin of any type.
All cents were struck at Philadelphia until 1908. At that time Philadelphia did not use a mint mark on any coins it struck, and even today cents do not carry a "P" mint mark - only D for Denver and S for San Francisco.
