I have (technically my parents own it) but I have a 1953 quarter. When you have is straight looking at the heads side you flip it over the tails side is turned to the left. Is it worth anything?
Without pictures I can't make a definite answer, but from your description it appears that what you have is a rotated die error. This happens when the two dies that are used to strike the coin are improperly orientated. The quarter itself is worth around $5 just in silver value. You could probably get someone to pay a few bucks over that with the error.
Thanks. I agree with your assessment. Imo the coin was just placed in the 2x2 at an angle. I am reposting the photos here so if anyone else stumbles across this thread they will be able to find them.
