Durango
During the Revolution coins were produced in Cuencamé and the city of Durango.
Cuencamé
The evolving history of the MUERA HUERTA coins is detailed here, while Ricardo de León Tallavas has recently confirmed that it was produced by General Calixto Contreras in Cuencame.
The coin is known in a number of varieties, and as a copper pattern.
KM-620. Variety with six stars.(Stack’s Bowers NYINC Auction, 13 January 2023, lot 21252)
KM-622. Variety with dot-dash border on the eagle side (Stack’s Bowers NYINC Auction, 15 January 2022, lot 2321)
KM-621 (Stack’s Bowers Auction, 12 September 2023, lot 73403)
KM-unlisted (Stack’s Bowers ANA Auction, 16 August 2016, lot 21405)
The above coin's unmistakable crisscross patterned edge design is similar to the one found on some examples of the very rare pattern type struck in copper (KM-UNL, GB-81) while the obverse (date side) die is a reworked, slightly refined version of the also very rare "mule" type struck in silver (KM-621, GB-85) with the date "1914" being the clearest tell-tale characteristic. It is thus quite logical to conclude that the present coin, albeit obviously well-circulated, constitutes a pattern or an extremely limited issue that should be chronologically placed after the aforementioned "mule" type and before the regular Muera Huerta issue (KM-UNL, GB-87).
Durango
These coins were commissioned by General Calixto Contreras after he captured the city in June 1913.
Although the coins were minted in the old mint the people in charge were inexperienced and so the quality of the coinage is bad.
One centavo
The 1c coin is known in various varieties. David Hughes discusses the different obverse and reverse dies here, whilst Angel Smith reports a new die here.
