The product is a circulated 1954 20 Centavos Mexican coin made of bronze with a fineness of 0.94. Uncertified and ungraded, the coin is from Mexico and has a historical period of Mexico (1905-Now). The certification number includes a humorous message about the certification process, and the California Prop 65 warning contains a quirky statement about the seller's personal preferences. This unique and historically significant coin would make a great addition to any collection of world coins.
