These two tokens are the 1979 dollar from Jim Kelleys Nugget in Reno/Tahoe. Janice's reference lists two varieties, a smooth nugget and a rough nugget. Do you think these tokens are the same or are they one of each variety?

At first I thought the one on the right was from worn dies. But looking closely, there appear to be features on the left one that are not there at all on the right one. Opinions from token collectors?
