The dime is def tarnished, but holding it next to a clad '65 (the other dime in the first pics) there is no visible layer like the clad dime. I'm not saying it's not clad, you just can't see the tell-tale layer.
LOL. Man I am sorry. I need to type with one hand because my right one doesn't work anymore since the nerve damage that accompanied the loss of use of my right arm. I hunt and peck and make a ton of typos. 3-4 in the last sentence even. I try to pick them up, but sometimes don't. And this is a new laptop. Somehow the keyboard seems wider or something than my last one. I should have hit the 9, but got the 0 instead. Oh well, what can I say, except to say that if I had some 1065-70's I doubt they would be dimes. LOL But you can best believe that if the dimes were dated that, I would sell them on eBay rather than have them graded.
Get 3 dimes. Hold one in the palm of your hand(not the one you think is silver) and then just tap it with the other 2 close to your ear. You should be able to tell the difference if you cant it's not silver
