1913 Mexico 25 Centavos Tesoreria General del Estado Chihuahua PCGS F12

Commonly known as the "Pancho Villa" note, this is that one note that all collectors want.  Not in the best shape but now preserved and ready to be added to your collection.  The photo from PCGS doesn't do it justice.  She's old but I'd still take her out for a drink and see where the night goes.
