I found this today. You can see WE TRUST. On the reverse it looks like UNUM at the bottom of the coin.
I’m not an expert but looks like someone slammed a coin on top of that one. You can sort of tell by the ridge. Paddyman98 might have a better take on it.
I don't think it's a simple vise job; the extra lettering isn't incuse, and isn't reversed, and I don't think it's imaginary, either. Let's raise the official @paddyman98 signal...
There is actually a find in,I believe Kentucky, by a coin dealer and his wife, of a coin with a second strike running in a curve along the inside edge of the coin.The found coin was/is referred to as a "Discovery Coin" , being the first known of it's kind. I really wish I could remember the source of that read. It was just this past few months when I saw it. I could swear someone linked to it here on Coin Talk !!
I was just reading some stuff online and I think the guy who found the Discovery Coin for the double strike is Jeff Garrett of Lexington, Kentucky.
Only the person that created it would know. All I know is that it is impossible to occur during the minting process.
you make a "die" press a coin onto another coin or flat sheet of copper .. and viola, you have yourself a "die" to press the correct orientation verbage onto another coin.
The obverse rim is a vise job, so I assume the reverse is damage also. As said above not possible. Reverse dies have been made from a gold coin, if the speed and force of the collision is high enough before the gold coin distorts.
@Profit man - stop doing this. Consider this a cease and desist warning. You will receive points if you do this again.
