I Found An Odd Indian Head Cent

That's for all the feedback, everyone.

jmkendall, I was wondering that as well. I would think by the time the rim was eaten away, the images on both sides of the coin would be more eaten away than they are. Anyone else care to offer a judgement on the coin?

The acid eats are all the surfaces at roughly the same rate so the coin keeps the details even as it becomes paper thin. The rim dissappears because one of those surfaces being eaten away is the edge of the coin. As it gets eaten the diameter of the coin gets smaller and the rim disappears. (The inner edge of the rim can't get closer to the center of the coin, but the outer edge does. When outer meets inner, no more rim.)

And if it was just struck on a thinner planchet the surfaces would still be smooth, the low relief details would still be present, and the high relief area would not show detail at all.
