First, a roll is #50 pieces. Second, your figures come to $8 each, which seems a bit high, unelss they are REALLY nice.
Did you look to see if they had full bands? How nice are they? Sorry, but "nice" is not a really accurate grade.
Thanks to all who have responded with your opinions. This would be my first opportunity to buy Mercury dimes. To give me guidance for buying dimes I went to the following site: http://www.coinfacts.com/dimes/mercury_head_dimes.html The description gave me good idea to judge the reverse but no help in grading the obverse. The dimes in questions do have Full Split Bands on the reverse. I am not too impressed with the splits in the central bands. In addition, the feathers on the Mercury, obverse, are not very impressive either. I have difficulty grading the obverse. I am trying to attach pictures without much success, but I will try again. I have purchased these coins with a condition to return in 5-days. Can some one please provide a pictures of a BU (MS 60) Mercury. This will help me make the decision. Thanks! Al
