2024, Year of Felipe Carrillo Puerto, Meritorious of the Proletariat, Revolutionary and Defender of the Mayab CIRCULAR 10/2024 Mexico City, July 19, 2024. SUBJECT: Modifications to the Cash Operations Circular regarding the circulation of a $20 coin, commemorative of the 500 years since the founding of the first Villa de Colima. TO CREDIT INSTITUTIONS: The Bank of Mexico, based on what is provided by articles 28, paragraphs sixth and seventh, of the Political Constitution of the United Mexican States; 2, 3, fraction I, 4, 24, paragraphs first and second, and 25, of the Bank of Mexico Law; 48 of the Credit Institutions Law; 1st, 4th, paragraphs first and fourth, 8th, paragraphs fourth and eighth, 10, paragraph first, 16 Bis, fraction II, and 17, fraction I, of the Internal Regulations of the Bank of Mexico; Second, fractions III and X, of the AGREEMENT establishing the characteristics of a commemorative coin for the 500 years since the founding of the first Villa de Colima published in the Official Journal of the Federation on March 22, 2024, has resolved to add numeral IV.II.3.9.21 and modify Annexes 15, 20 6/6 and 26 4/4, of Circular 9/2023 on Cash Operations (Circular).

The modifications to the Circular aim to put into circulation the twenty pesos commemorative coin of the 500 years since the founding of the first Villa de Colima, of current strike, which will coexist with the twenty pesos banknotes and metallic coins currently in circulation, which are identified with key 959. In view of the above, credit institutions must make their deposits at the Bank of Mexico, in accordance with what is established in Chapter VI, of Title II, of the aforementioned Circular, separating the new commemorative coins mentioned from those with key 810, whose shape is circular, diameter is 32.0 mm (thirty-two millimeters) and total weight of 15.945 grams, which differ from those of the cited commemorative coin.

Likewise, it is important to reiterate that, since August 8, 2022, the Bank of Mexico can accept dodecagonal coins, indistinctly, those with key 941 and whose content per bag is 500 pieces or those with key 959, whose content per bag will be 700 pieces. Therefore, credit institutions may make their deposits at the Bank of Mexico combining commemorations in bags of 700 pieces. This without combining the dodecagonal coins with those of circular shape.

In conformity with the Decree, as well as with the design determined by this Issuing Institute, the new coin will have the following characteristics: I. Nominal value: $20.00 (Twenty pesos 00/100 M.N.). II. Shape: Dodecagonal. III. Diameter: 30.0 mm (thirty millimeters). IV. Composition: The coin will be bimetallic and will consist of two alloys, one for its central part and another for its peripheral ring, which will be as follows:

1. Central part of the coin: Silver-plated alpaca alloy, which will be composed in the following terms: a) Content: 65% (sixty-five percent) copper; 10% (ten percent) nickel, and 25% (twenty-five percent) zinc. b) Tolerance in content: 1.5% (one, five tenths percent) per element, more or less. c) Weight: 5.51 g. (five grams, fifty-one centigrams). d) Tolerance in weight per piece: 0.22 g. (twenty-two centigrams), more or less.
2. Peripheral ring of the coin: Aluminum-bronze alloy, which will be integrated as follows: a) Content: 92% (ninety-two percent) copper; 6% (six percent) aluminum, and 2% (two percent) nickel. b) Tolerance in content: 1.5% (one, five tenths percent) per element, more or less. c) Weight: 7.16 g. (seven grams, sixteen centigrams). d) Tolerance in weight per piece: 0.29 g. (twenty-nine centigrams), more or less.
3. Total weight: It will be the sum of the weights of the central part of the coin and the peripheral ring thereof, corresponding to 12.67 g. (twelve grams, sixty-seven centigrams), and the tolerance in weight per piece will be 0.51 g. (fifty-one centigrams), more or less. V. The dies will be: Obverse: The National Coat of Arms, with the legend "ESTADOS UNIDOS MEXICANOS", forming the upper semicircle. Reverse: Colima, to the right the colimote dogs, also known as dancing dogs, and in the background the silhouette of the volcano of Colima. To the left the image [Note: Text appears truncated or garbled here in source regarding specific image description, but retains structure]. VI. Edge: Discontinuous reeding. VII. Security elements: Latent image and micro-text, according to the description of the reverse of the coin, which must be related to its motif.
