Pirates were often compensated for loss of a limb or eye. It was written into the ship's constitution the value of each loss. Since most people are right handed a limb on the right side was valued more. For example the loss of a right arm would go for 600 pieces of silver while losing the left arm would get 500. The right leg might get 500 and the left one would be compensated for 400. Loss of either eye would get 100.
