Rotated Die Quarter

Not bad for pocket change find I guess

Not bad at all.

Thats an excellent find, I found a 104 degree rotated Canadian nickel in MS+ condition when I first started out in coins. I got $239. for it on ebay. It was a 2007 and I wish I kept it now, cause I sure haven't found anything even close since..lol

Correct.

It would not be a new discovery. But it is one you might like to have slabbed if you were going to sell it. If not make sure to keep it safe in a special place. It would be a coin with a premium for it. Slabbing would give you a grade that you could use when you sell it.

I was told in another thread that In numismatics we measure the smallest degree of rotation from the 12 o'clock position because the die could have rotated either direction, is this true?

The way I've always practiced it, and the way I've always seen it done begins with the reverse design pointing south, which is the position you find the reverse face when you flip a coin from left to right. Any die rotation error is then assessed from 1 - 180 degrees, clockwise or counterclockwise. Any rotation toward a clock position greater than 6:00 is considered a clockwise rotation. Any rotation toward a clock position less than 6:00 is considered a counterclockwise rotation.

Naturally, identifying a die rotation error as a rotation of the reverse face relative to the obverse face is simply a convention adopted for the sake of convenience. In any simple die rotation error, there is no way to determine which die rotated. However, die rotation errors combined with other errors almost always implicate the hammer die.
