The obverse design features the Mexican coat of arms, an eagle clutching a snake while it perches on a prickly pear cactus. On the outer periphery is the phrase “REPUBLICA MEXICANA”.
The reverse design features the denomination “1C” encircled within a wreath with the year of issue at the top and the mint marks “M” for the Mexico City Mint or “C” for the Culiacan at the bottom of the design.
General Market Notes
Excluding proofs and errors, the key to the series is the 1899-M issue and the semi-key is the 1905-C issue.
Krause catalog information may conflict with the diameter & weight shown here. This site has measured and weighed 16 different coins from both mints and all coins measure 20mm & 3 grams. The Krause catalog goes further by assigning two different catalog numbers (KM# 394 and KM# 394.1) for the series implying that there are distinct varieties but the only difference between the two are their mint marks.
