Someone else asked if you could post photos. Without them, it's not worth anything but an opinion. Chris
Its not a cent, its a Jefferson nickel. I tried finding similar errors, but was not even close. Dream? No, mercenary. If its worth enough, then the monetary value exceeds its keeper value. Given a ballpark idea, I might dig it our and sell it.
I can't seem to find a image of the uniface Indian cent pair that I examined once, but ran across this. How in the world does this happen on proof coins if not intentional by a mint employee? http://coins.ha.com/itm/errors/1972...niface-reverse-coin-2-pr65-pcgs/a/1216-6645.s
Thank you! That's what mine looks like, only its the obverse stamped, while the reverse is blank. Twins? Mine is no 5. I found it in pocket change, although its not worn and hideous either. I kept using different forms of "blank" in my searches, not knowing they had a specific name. I have no idea how they happen, and presumed it was two planchets in the press, each receiving one side press only. I had hoped someone with a better knowledge of mint processes could explain or verify
There are a couple of ways that it can happen, but we would need to see what the blank face of the coin looks like to determine how it happened. I would say that most if not all ways that it could happen at the mint would leave the blank face pretty distorted. If it is completely flat and smooth, it has likely been tampered with. I should also note that even though I have a working knowledge of errors, I am by no means an expert but others here are. They may just be reluctant to offer an opinion without seeing it first.
I will venture to say that a coin struck by a capped die could also have a uniface appearance. Pictures are needed for an accurate assessment.
