Special Mint Set Roosevelt Dime - Type 2 Clad, 75% Copper 25% Nickel  only 2,360,000 minted in San Francisco

Not a graded coin, I can't say it's a SP__ SMS  which is considered now the PR series,

 because I'm not a professional coin grader but I'd say it's above the mid number. You be the judge.

  Excellent old coin now in a 2-1/2" square coin Saflip, No more staples here they can cause damage.

I took multiple pictures to try and capture the true shine and cover the angles.
