FREE: 1966 ROOSEVELT DIME ERROR COIN

This coin was purchased from a very well known and respected coin dealer, I have no reason to doubt him? but I don't want to mislead anyone either, I am not a coin expert by any means, my husband is a numistmatist and is trying to teach me, (long process lol.) they are a very picky bunch and will spot things that are so slight no one else would notice, so hopefully who ever wins this won't be disappointed in what they get. Thanks for your input, and I realy mean that

The line across the face is due to something on the die when the coin was struck. IT IS NOT A SCRATCH thus the defective die, a "reverse flip off" is where when the coin was flipped to make the reverse strike was shifted slightly and the reverse is not in alignment with the obverse. By what % I can not say, but is slight. Like I answered the other guy Numistmatics are a very picky bunch and find all kinds of things on a coin that other collectors don't notice. If the winner of this coin does not like it they can always mail it back and I WILL REFUND CREDITS WHEN I RECEIVE THE COIN BACK. I am not trying to mislead anyone about this coin and will not be putting anymore ERROR COINS UP FOR AUCTION .
