    I was just curious on what everyone thought about this. I got this half dime in a lot and flipped it over north to south and the reverse is upside down and is at a slant as well. Almost a full rotation. If it's of course flipped west to east it shows the reverse right side up but also still at a slant. Too bad it isn't in better condition. How much do you think something like this would be worth and if I sent it in do you think it would change the value much? I've had die rotation errors before but never something that's View attachment 1688039 View attachment 1688040 almost a complete 360. What do you think the alignment (degrees) is on this? I need to order a die rotation measure. I've added pictures. The last picture is with it being flipped vertically. It's the best I could do, sorry.

    Nice one Bone Dust! Have you checked to see if that is a variety/die pairing?
    Hey, flatten those staples.

    Cool coin! Get a Flat clinch stapler so Pickin and Grinin can sleep tonight.

    That depends on whether you measure the Die Rotation clockwise or counter-clockwise. Actually the largest rotation a coin can exhibit is 180 degrees.

    I'll check on that. I threw it in the flip and stapled it fast just to show how i was flipping it.

    Ahh yeah. I meant 40 degrees then as i flipped it top to bottom instead of left to right last time. Or maybe i'm just not doing it right at all as I rarely come into contact with this sort of error. This is only the third time. And 40 is the opposite of 220.

    Hehe. I took it out of the flip and put it in a plastic one so I could easily take it out if needed. Don't worry, it is safe and will be under my pillow while I sleep.

    I did have one but it broke. I need to order a new one online. Maybe I'll just do that now.
