How much does a die need to be rotated to be of value as a rotated die error? I found these two pennies, but they aren't rotated much.
Yours are not rotated enough. Here is an older thread about mint tolerances for rotation: https://www.cointalk.com/threads/rotated-die-us-mint-official-tolerance.330856/
I asked the mint what the tolerance was for die rotations. Here is their answer: "For circulating denominations the coin rotation tolerance is typically: +/-6⁰ For numismatic (proof coins, precious metals, commemoratives, etc.) denominations the coin rotation tolerance is typically: +/-3⁰" The most popular rotations are the 45⁰, 90⁰ and 180⁰ rotations. Collectors show little interest in rotations smaller than 45⁰, except for proofs which will start at about 20⁰.
I didn't know what the heck I was looking at until I read your post! It looked like the coin was cut in half!! Thanks!
I gotta find a small enough rubber band to go around the coin. Stby.... @Kaye- Can I post it here if I find one?
Not a major rotated die but it's noticeable. This coin is in my 7070. I first noticed it a few years ago when I turned the page!
Nice. FWIW back in the day, dies were held in place with setscrews and if the screw loosened they could rotate. Modern dies are machined so that they aren't supposed to rotate. For example, see: https://images.pristineauction.com/...om-United-States-Mint-PristineAuction.com.jpg
