Guerrero. Revolutionary Mint Error 2 Pesos 1914-GRO About Good, Guerrero mint, KM643. Struck an irregular flan. An infamously crudely produced issue, this intriguing error appears to have been made on a rolled, handmade flan in great haste. Though the majority of the detail has been obscured by the nature of its production, traces of the integral features remain, and seem to grant a great degree of historicity.
