Great article. I'm still looking for that elusive 1906-S Peso. Due to its rarity a lot of counterfeits are out there. As a side note, the model for the standing female figure was the designer's (Melecio Figueroa) 10 year old daughter, Blanca, whom he portrayed as the young woman he imagined her to become.
Just curious why you didn't complete the specifications list up to the Peso
