Theriena... First off, welcome to the Treasure Net Forums and I am sorry that I did not welcome you in my previous post! Second, I am sorry to say that IMHO, the coin is not a Repunched Mintmark Variety. It appears that the area to the Southeast of the "D" mintmark took a hit, exposed the Zinc core and corrosion & the elements created what can be confused as another "D" mintmark. As you can see, the actual "D" mintmark also took a hit on it as well and corrosion & the elements have made it almost unrecognizable. Don't give up, you will eventually find a coin that is a Repunched Mintmark or other Variety. It took me a long time before I got in tune on knowing what to look for and finally found one, then two which grew into dozens, then grew into hundreds of them.
