Guatemala, 1 peso, 1873P, no period in fineness. KM-197.1. 25.34 grams. AU with rainbow toning. Fineness reads "0900" rather than "0.900". This issue was struck on a 25.4 grams standard making it heavier than the French official standard per the law of 1869, causing the French-standard coins to circulate instead. ($150-225)
