From 1965 to 1967, the U.S. mint suspended mint marking of all coinage. Thus, your 1967 dime is a normal dime, which happens to be from that year range. As such, I will reference an excellent answer to the general worth of coins:
"As with any collectible, a primary consideration in determining its value is its condition (or grade). Novice collectors, with some practice, can become quite accurate in determining grades for circulated coins (G-4 through AU-50). It becomes much more difficult when assigning grades for Uncirculated coins (MS-60 through MS-70) or Proof coins (PF-60 through PF-70) and the assistance of an experienced coin collector or trusted coin dealer should be sought. Another consideration is whether the coin has a mintmark, indicating where the coin was made: D = Denver O = New Orleans S = San Francisco CC = Carson City Coins struck in Philadelphia generally do not bear a mintmark. There are other mintmarks, but the above list covers most. There are many internet and printed resources in helping determine the appropriate grade for a coin. Whichever resource you choose to use, ensure that they follow the grading guidelines established by the American Numismatic Association (ANA)."
The coin is only face value. No U.S. coin dated 1965,1966 or 1967 will have a mintmark.
If the coin is the same thickness as a regular dime it's been plated and is only worth face value. If it's thinner than a regular dime and is copper on one side only, the cupronickel cladding un-bonded from the core. This is called a lamination error and is worth around $5 or $6 Note there's no such thing as a 1967-P dime because US coins dated 1965, 1966, and 1967 don't carry mint marks.
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.
About $1.50 at current silver prices.
It's worth 10 cents.

Check that coin again. No coins that year contain a mint mark, nor did the P mint mark appear on dimes until 1980.
