Best Answer

No. The US Mint in San Francisco has produced many coins for circulation since it opened in 1854. Prior to 1968 nearly all proof coins were made at the US Mint in Philadelphia, Pennsylvania. Beginning in 1968, all proof coins were produced at the US Mint in San Francisco although this mint continued to produce Lincoln Cents for circulation until 1974 and Jefferson nickels until 1971.

In 1984 the US Mint at West Point, New York began minting proof coins as well.

The Philadelphia Mint also produced proof $1 coins in 1999.

What is the value of 1981 US coin proof set?

The 1981 Proof set has a current value of $9.00 and issue price was $11.00 but check the "S" mint mark on all the coins, on most of the sets the mint mark is filled an does not appear well defined. If all coins have a sharp clear mint mark, value may be $300.00 or so.


What is s?

I assume you posted this in the Coins and Currency section because you're referring to the S mint mark. On U.S. coins, it means that the coin was struck at the San Francisco Mint. San Francisco struck coins for general circulation up to 1955, then occasionally (and only cents and nickels) from 1968 to 1974. Currently only proof coins are made there.

1973 silver dollar?

The series of Eisenhower (1971-1978) dollars can be confusing. None of the coins released into circulation contain any silver, people call them silver dollars just because of the size of the coins. The Mint did make special collectors coins that are 40% silver from 1971 to 1976. These coins were not released into circulation and all have "S" mintmarks, but not all the "S" mintmarked coins are 40% silver. The mint also made copper-nickel Proof coins with "S" mintmarks for 1973. To add to the confusion, 1973 was the only year the regular copper-nickel coins were not released into circulation. They were only issued in the Uncirculated Mint Sets sold from the Mint in 1973. Post a new question and include the mintmark if it has one. Also if it's in a plastic case.

Where is the proof mark on a walking liberty half dollar?

There isn't anything on a coin called a "proof mark". There are MINT marks, small letters that indicate which mint struck the coin. Proof coins are specially-struck and sold in packages to collectors and investors. Up to 1964, most proof coins were made at Philadelphia and didn't carry mint marks. Since 1968, proof coins (with a couple of exceptions) have been made in San Francisco so they carry an S mint mark.


Do Ike silver dollars with a s mint mark have silver in it?

For 1971 & 1972 only, all S mint marked coins are 40% silver. From 1973 to 1976 the S mint marked coins in the standard proof sets are clad coins, the 40% silver Ike's were sold separately but they were included in the bicentennial 3-piece silver sets. No silver Ike's were struck in 1977 or 1978.


Is there a 1973s Ike Dollar that is solid silver?

Solid silver? No. The silver clad Eisenhower dollars are all 40% silver. But for 1973 not all S mintmarked coins are 40% silver. The San Francisco Mint did strike copper-nickel proof coins that were included in the proof sets for 1973. The 40% silver coins were struck as proof & uncirculated but were sold separately, so 3 different S mintmarked coins were struck in 1973.


Where are S mint coins from?

The "S" mint mark is used by the San Francisco Mint. Today San Francisco makes proof coins sold to collectors, but for many years they produced coins for general circulation as well. All denominations were made until 1954, dimes and cents were made in 1955, cents and nickels were made from 1968 to 1974, and dollars were made in 1979 and 1980.

What is the value of a 1961 S US cent?

Please check your coin again and post a new, separate question. The San Francisco Mint was inactive from 1956 to 1964 inclusive, so there are no 1961-S coins of any denomination. The SF Mint was reactivated to strike Special Mint Sets and some circulating coins beginning with the 1965 dates, but these coins didn't carry mint marks. The S mint mark was resumed on proof coins beginning in 1968. In addition, SF minted some cents and nickels for circulation from 1968 to 1974; all of these also have an S mint mark.


What does San Francisco mint mark look like?

Uh, a small "S" ! San Francisco struck circulating coins up to 1955 and then again sporadically from 1968 to 1975. Since 1968 all proof coins except 1999 dollars have been made there and carry an "S" mint mark.
