Guerrero's 1915 copper issues were struck under the authority of Zapata's Ejército Libertador del Sur, which operated its own provisional mints as federal supply lines collapsed entirely. The Chilpancingo mint produced these pieces from whatever copper was locally available, which is why composition and weight vary noticeably across surviving examples — the 6g figure is a target, not a guarantee.
Zapata himself was assassinated at Chinameca hacienda in April 1919, and within months the revolutionary coinage his movement had produced became purely commemorative by circumstance.
