Die Cracks Error 1896 Mexico 8 Reales Bu Unc ERROR World Silver Coin SEE PICTURES. This coin is not graded but based on my personal opinion I think it deserves a grade of 64 or even 64+ but I will admit it shows some signs of cleaning. The die crack error on the coin is extremely evident if you take a look at the pictures and shows up in multiple spots on both the obverse and reverse of the coin.
