I need some help. A person on another forum found a 2000 d dime. he thinks it is a mint error. i can find no evidence that it is a mint error. i will post images below. i would like to help him out because he thinks he has a big find. the edge of the dime is smooth no reeded edges. http://trivialtreasure.blogspot.com/2011/04/found-interesting-dime-2000d-smooth.html you can click on the pictures for a zoom. i can find only one other person that has found something similar and the conclusion is that it has been plated. has anyone else seen or heard of anything like this? i just read a thread below could this be a dryer coin?
