I have a unique Jefferson Nickel in my collection, I just rediscovered it in a roll of 1938-64 nickels (I usually save these years just because they are old-so I pull them out of circulation when I see them). I have a 1964 Jefferson that almost looks proof to me, but there is something unnatural about it. I wonder if it has been retoned or dipped or something. I remember when I first found it I was intreged by it. So, I guess what I'm asking is this an older proof that has seen a little circulation or has someone put something on it to give it the unnatural appearance. Any thoughts? I don't really think these pics are that good but it was the best I could come up with-hopefully they will do. It doesn't really matter, I'm asking more out of curosity because the coin is worth about $.05 either way-I've just had it for a long time and have always wondered about it.
I've seen this kind of effect before in Jeffs that have been in contact with plastic or cellophane for many years. Leave them against it long enough and they will start to gain irridescent colors and look proof like.
I never noticed that this nickel was cameo until I took these pics today.None of the 1964 proof sets that I own have ANY cameo coins in them,and it's been in my Jefferson album for years.If it weren't for the spots on the obverse,I'd be tempted to submit it for grading.
Not sure about that 64 Nickel but probably was an experiment in polishing. If it was ever a proof, to late now.
Just about all of the Proof Jeffs from '61 thru '64 are known for this type of toning. It happened less often from '68 through the early '70s, but they can be found. I once purchased a lot where every single coin, 120 of them, all had the same type of toning in various shades. I gave most of them away as gifts to those who like toned coins.
