I have a 1969 D dime. Obverse and reverse seems to double struck. Obverse at the top around the rim. Reverse bottom around rim. I have several 1969 D dimes. This is the only one that is like this. Can't find anything online about this type of error.
I have one quit similar, I can't find any information on it. I would also like to know more about it I'm also unsure how to upload pictures.
Nobody answered this thread back in 2019. But I will now. It is not a double struck issue. It's a simple Misaligned Die Strike. Many Dimes have this issue. Probably yours also.
