This is a Mexican fiscal (revenue) stamp issued in 1909 with a denomination of 12 Pesos. Printed in red with bold inscriptions, it was used for “Control del Talon” (control of receipts), specifically for patents, direct accounting, and waybills. The stamp features a prominent serial number (01683) in black at the top, which ensured accountability in tax collection. Such issues were not valid for postage but played an essential role in Mexico’s fiscal system of the early 20th century. Collectors value these as part of the broader field of revenue philately, reflecting the country’s economic and administrative history.
