As of 07/2009 retail values are over $15,000 for a 1968 proof set where the dime does not carry a mint mark. That was the first year that proof coins were struck at the San Francisco mint, and one of the die-makers forgot to put the "S" mint mark on a die. Some "S-less" dimes were shipped in proof sets before the error was discovered. Be careful, though. Normal 1968 Philadelphia dimes don't have a mint mark because the P wasn't used on dimes until 1980. A Philadelphia dime can be processed to resemble a proof coin.
A 1968 dime with no mint mark is worth its face value of 10 cents if it's in circulated condition. However, if it's in uncirculated condition or if it has any unique features or errors, it could be worth slightly more to collectors, typically ranging from a few cents to a couple of dollars. In general, most standard 1968 dimes do not carry significant numismatic value.

10 cents. All circulating dimes dated 1965 and later are made of copper-nickel so they have no added value, and can be found in normal change. The only valuable 1968 dime was an error that occurred in some proof sets. 1968 was the first year that proof coins were struck at the San Francisco mint, and one of the die-makers forgot to put the "S" mint mark on a die. Some "S-less" dimes were shipped in proof sets before the error was discovered.
1848 Half Dime, with Med. date, in good condition is worth $8.00, uncirculated is worth $185.00. 1848 Half Dime, with Lg date or O mint mark in good condition is worth $10.00, uncirculated is worth $400.00.
It's worth exactly 10 cents.
The missing mintmark 1968-S dime is only found as a PROOF coin in the 1968 proof sets. If you think you have one of these coins that has been removed from a proof set, it would have to be authenticated by a major grading service.

1941 Winged Liberty Head/Mercury Dime: With no mint mark, in fine condition is worth $0.70, uncirculated is worth $17.00, proof is worth $175.00. With D mint mark, in fine condition is worth $0.70, uncirculated is worth $17.00. With S mint mark, in fine condition is worth $0.70, uncirculated is worth $20.00.
No. The US Mint produced over nine hundred million 1968 Roosevelt Dimes without an "S" mint mark. Unless it is truly a Proof dime from San Fransisco. It would be more than likely in a proof, unopened set. Apparently, they produced the proof coin (which started in 1968 in San Fran) missing the mint stamp. They caught it but some got out I guess. I think that is where the confusion stems from. This coin didn't have a mint mark from one of the other mints.
The very distinct difference is that if it doesn't have a mint mark it was struck in Philadelphia. The P mint mark wasn't used on dimes until 1980. If it has a D mint mark it was made in Denver. Both are only worth 10¢ if found in change. If it has an S it's a proof dime struck at San Francisco and only sold to collectors.
10 cents. It is struck in copper-nickel and unless it is a proof coin or in a special mint set, it has no collector premium just like any other dime struck after 1964.

Average value is $15,500.00. If you think actually you have one. It must be certified as authentic.
There have not been any silver dimes struck since 1964, except in some proof sets. If your coin has an S mint mark on it, it's worth about $1.15; it would be worth more if it were in its original proof set package. If your coin has a P or D mint mark it's an ordinary copper-nickel dime that has been plated to look like silver. It's only worth 10 cents.
About a dime.
The S mint mark on a dime dated 1984 indicates that it was a proof dime minted in San Francisco for inclusion in special sets sold to collectors. My guess is that someone broke up the set and spent the coins for face value .... not a wise move, because what was formerly a coin worth maybe 60 cents as part of a set worth 7 or 8 bucks, is now only worth a dime.
