MEXICO  4 REALES  1556-98  MOO  KM- 36  GRADED  NGC 35 VERY FINE!! THIS IS THE NICEST "CROSS SIDE" WE'VE EVER SEEN, ESPECIALLY WITH THE INCREDIBLE CENTERING (FRONT & BACK)!!!  THE COMPLETE CROWN IS VISIBLE ON THE FRONT AND STILL SHOWS THE LEGENDS – VERY VERY UNCOMMON!   ON THE REVERSE (CROSS SIDE) IT DISPLAYS THE MORE ORNATE CROSS (LOOKS MORE LIKE TEMPLAR CROSS), ALSO DISPLAYING THE LEGENDS (YOU CAN READ:  KING PHILIP OF HISPANRVM AND THE INDIES). WHAT'S REALLY RARE IS TO BE ABLE TO CLEARLY SEE THE CASTLES AND LIONS (REPRESENTING THE KINGDOMS OF CASTILE & LEON).  THE PLANCHET / FLAN IS VERY NICE AND ROUND.  GREAT STRIKE ON THE SHIELD AS WELL, ESPECIALLY FOR 450 YEARS OLD, NICEST WE'VE EVER SEEN!!!
