http://www.doubleddie.com/154201.html Interesting! Below copied from Wexlers- Comments: This abnormality is being found on both Philadelphia and Denver Mint coins. It is not certain at this time whether a doubled working hub is involved or if it is something in the design itself that does not manifest itself on all dies. Either way it should ultimately prove to be too common to have any value beyond the normal numismatic value of coins in this series.
