Hello
The part of back is flat, perhaps tube shape of sostenense but not there now. The size is like a tennis ball. The image is a Sun, and is from Peru or Argentina called "The cayao Sun" animal is a lion with Eagle's head is an animal mythology is called " Grifo" the only thing I can't find is the shield. This island where I found this medal close to Cuba and that was the route I had to take gold in Latin America to the old world. Is all the information I have. I am interested in selling it but I want information to not be wrong with the price. If it does not cost much money was it me for the future
