I AM LIQUIDATING MY COLLECTION.  This is a 1948 half sol from Peru which is both DOUBLE STRUCK and OFF CENTER.

I am reasonably certain that this coin is UNIQUE.  NGC has graded only 4 other coins in a higher grade but NONE of those are mint errors..  This specimen has an elongated planchet, is 50% Off Center and is DOUBLE STRUCK.  

This coin is UNIQUE, Unusual and Beautiful!  It has been in my possession since 1961.
