Is there any way of knowing right off the bat if the 1965 roosevelt is one of those rare ones minted in silver? I don't have a scale to weigh the dime & I haven't been collecting long enough to trust my ears to see if it makes a different noise when I flick it. I only ask because I got a 1965 dime in change yesterday. And I noticed that it looked different than the 1965 dime I had at home. I decided to do that "napkin test" on both to compare and contrast. The original one I had at home passed the test ( in other words, it reflected more light than the other, which is supposed to mean its silver). I won't be able to get to a coin shop for an expert eye until Tuesday. -O.A.V.
