Carib.C. 10 Pesos 1992 - Ptolomeo and Toscanelli Proof / Silver

Based on the letter of Toscanelli, and his map showing the route to Orient crossing Atlantic ocean, Columbus planned his trip to Catay and Cipango (China and Japan). That map was based upon the calculations of Ptolemy, that had big mistakes on distances, ending on an esteemed position of Orient, much shorter than real, cause he esteemed the diameter of Earth as 29 000 km instead of the real 40 000.
