In general no. Prior to 1980 only the D&S mintmark's were used. Coins struck at the Philadelphia Mint did not use a mintmark. From 1980 to date the Mint added a "P" mintmark. But some Proof sets have Dimes that lack a S mintmark, they do have much higher values.
The most valuable is a error coin, the 1982 dime with no P mint mark. It has a value of $110.00
According to the US mint, 1.676 billion dimes were made in 2012.
None, no gold dimes have ever been made by the US Mint.
Yes. All 3 mints struck dimes in 1952
1965 dimes don't have a P mint mark for 2 reasons. First, Philadelphia didn't use the P mint mark on dimes until 1980. Second, during the coin shortages of 1965-67, the Mint suspended the use of all mint marks including D and S. That means you have an ordinary dime worth face value only.
The US didn't mint any dimes dated 1817.
The US Mint did produce any dimes in 1819.
No. The US Mint produced over one billion Roosevelt Dimes for circulation in 1970.
Roosevelt dimes from 1965, 1966, and 1967 were minted in large numbers to replace the silver dimes minted up till 1964. They're still found in change and have no added value in circulated condition. Uncirculated ones are worth $1 - $2 each. Note that there are no mint marks on US coins with those dates.
The mint mark (if it has one) is on the reverse, along the rim, at about 7 o'clock, just to the right of the "E" in ONE. It's in the same place on all years of Mercury dimes. Possible mint marks are: (none) = Philadelphia D = Denver S = San Francisco

It's actually an intertwined A+W, and is the monogram of the coin's designer A.A. Weinmann. It appears on all Mercury dimes regardless of date. Monograms on older US coins cause a lot of confusion. Most coins had their mint marks on the reverse (back) side until 1964. Because all modern coins have their mint marks on the obverse (front) many people think that the older monograms are mint marks.
