So far as I am concerned, the anomalous Peruvian 5 Pesetas of 1880 is the coin to beat in this category.
My specimen is not the best, but I like her anyway. Look at those big hoops!

Here is my scan of a black-and-white photo of another specimen (one of a group of photos I came into possession of, which I think was part of someone's collection inventory). The wear on the high points is very similar, but there is much less contact-marking.
