Knowing what you do about the minting process... If a "modern" U.S. coin has a complete obverse, it is physically impossible to have a "blank" reverse without post-mint damage, right? http://www.ebay.com/itm/162561531641
Not impossible, but improbable. I coin struck with 2 blanks in the chamber will produce 2 uniface coins. One with an obverse and one with a reverse. Nearly always, there will be some faint impression of the missing side. As always - you need the weight. Make sure it is within specs. This is the best example I have - not a common coin, but not particularly valuable.
The con has been milled flat possibly to be carved into a love token that never happened. the first give away is that the rim which is set before pressing the coin is missing on the reverse. Richard
I realize that this particular coin has been milled, but what I'm postulating is that it is physically impossible for such a coin to exist. Am I correct?
The coin does not exhibit machine marks, but appears to have been clamped in a vise at 4:00 & 10:00. and filed to remove the reverse design.

Nope, as Old error guy points out it IS possible and he is correct as to how it can happen. But the key thing it the blank side will NOT be completely flat and smooth, and I believe the upper coin of the pair will also often be a partial collar error because both planchets won't fit completely into the coining chamber.

Something that I think is important to note is the fact that if you look at the "blank" side of olderrorguy's coin, the rim is upset.
Actually, ANACS agrees with you. Of course, they put that on everything they don't understand, which is no small number. I think the impression is too deep for that, which is easier to see in person.
I have a 1863 indian head penny missing the back. The front is just a couple degrees off center. The back has no edge imprinted at all, but if you tilt it you can notice the entire edge is uniformly got the slightest shiny edge on it. It weighs the same as my other penny. Is this a real penny ? does anybody know anything
