Chihuahua, Mexico, cap-and-rays 8 reales, 1874/1MM. DP-Ca50; KM-377.2. 26.8 grams. Overdate variety and possibly MM over inverted MM, not a die match to the 1871-Ca MM/inverted M published in DP but perhaps an unused 1871 die recut for 1874, an alternative theory being that the "4" and "MM" are all repunched but the base of the numeral below 4 looks too thin. AU with light cleaning, choice toning. ($100-150)
