The only variety of a dime from 1965 was the one without a mint mark produced by the Philadelphia Mint — but a lot were minted.
The 1968-S Roosevelt Dime without the mintmark (“No-S”) is a proof error coin that can be highly valuable. Since its inception in 1986.
A few 1970-S Roosevelt Dimes were mistakenly struck without the mint mark, making them valuable to collectors. Coin Appraiser has this coin valued at approximately $250.
Here is a good example of a regular coin worth regular money. CoinTrackers.com estimates the value of a 1972 Roosevelt dimes in average condition to be worth 10 cents, while one in mint state could be valued around $36.
The 1975 No-S proof Roosevelt dime is one of the most valuable of all modern coins. Just two known specimens exist. The most recent sale raised nearly a half-million dollars ($456,000) due to its scarcity, per CoinValueChecker.
The 1996-W Roosevelt Dime was a special issue to mark the 50th anniversary of the Roosevelt dime design. Its limited mintage (1.457 million) makes it relatively scarce.
A true oddity. The Philadelphia mint made over a billion dimes in 1998, so even an uncirculated coin from this year can be yours for a couple of bucks.
While one of these “Type 2 Clad Regular Strike” error strike dimes sold in “brilliant uncirculated condition” for $14,375 in 2009, one in average condition will only net you only a few dollars.
