Black Beauty Nickels of 1958 and 1959
As far as I know the reference of the "Black Beauty" Jefferson nickels only refers to nickels that were only minted in 1958 and 1959 at the Philadelphia mint. These coins IMO should only be bought in unc. condition. There is more than one person putting up all kinds of coins that were in the ground for awhile and turned black from corrosion and calling them "black beauty".
There are many other dates and denominations that have "Improperly annealed planchets" but they are not designated as "black beauties". Black Beauty is reserved for the 1958 and 1959 Jeffersons, I believe, Let me know if I am wrong. Does PCGS use the "Black Beauty" designation? Bob
