PERU. Independence Commemoration/San Martin Tribute Silver Medal, 1863. NGC MS-64. Fonrobert-9135. An incredible example that is sitting on the edge of Gem status. Full cartwheel luster is in effect and a bold strike on the popular sunface design. Truly, a fitting tribute for Jose de San Martin, who till this day is often referred to as El Libertador for his role in obtaining independence for Argentina, Chile and Peru.
