1839-O Half Dime - Major Die Rotation

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.

I used an online measure at forvm ancient coins and its showing it is off by 210-220 percent.

 

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.

 

We wouldn't want that, right?

 

You don't want me to sleep?

 

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.

 

I looked into the die pairing but the reverse is so weak that it's hard to distinguish anything. Are there any references online I would be able to go too? I haven't found any.

 

I am not really a seated guy.
There is this site.
The Definitive Resource For Liberty Seated Dime Variety Collectors
Liberty Seated Half Dimes With Varieties, Business Strikes
I think that @Publius2 collects these.

 

Thanks for the information. I'll look into it.

UPDATE: I contacted Gerry at the site and gave him much more updated pictures along with ones using my scope. Hopefully he can give me more information on this and maybe, just maybe, it'll be added to the list.

 

I have added more attachments with perhaps better pictures.

 

Update. I ordered coin rotation measurement tool from ebay and when flipping the coin from left to right it shows the rotation at approx 150 degrees.

 

Questions are: How common are these on this coin for the "era" we are talking about and two,: Which die is rotated? Working die or stationary one?
