My comment is in reference to: 1915 Mexico Peso Guerrero/Taxco (star before Peso & G) KM# 672. See photo. The legend reads in part, "ORO: 0.300" Both the Standard Catalog of World Coins and the NGC price guide state, "Coin is 0.300 fine gold" However, CoinfactsWiki states," The legend "ORO 0.300" does not mean 30% gold, but 0.30 grams of gold. There is a "G" above the "ORO: 0.300" and it would be redundant for it represent "Guerrero" as Guerrero is identified immediately above the "G". So, it makes sense that it would represent "grams." There is a significant difference between .3 grams and 9 grams (30 grams total wt. x .30) I have not been able to determine for certain which is correct. My guess would be it is .3 grams and NGC and the Standard Catalog are wrong. If there is an expert on Mexican revolutionary coinage that knows the answer, I would appreciate your thoughts.
I can tell you that later Mexican pesos that are silver say 0.720, which is the silver purity of the coin, so it would make sense that the same is true with your coin's gold content. That's all I know.
Thank you for the information and your taking the time to post it. After posting my question, I found an old article titled, "Gold in Revolutionary Coins" that specifically addressed 1914 and 1915 Guerrero Pesos. It did not surprise me that this coin had 0.30 grams of gold instead of being 30% gold because of the "G" above "0.300" as mentioned in my original post. I was confused by the NGC price guide and the Standard Catalog stating "Coin is 0.300 fine gold". What did surprise me in the article was that a 1915 Co Mo Mexico 2 Pesos Guerrero/C. Morado was not 0.595 fine gold as unambiguously stated on the reverse of the coin (ORO: 0,595) but instead, contained 0.595 grams of gold (or less actually). I find Mexican coins very interesting and the Revolutionary Period coinage particularly so. Thanks again.
I have several Mexican silver coins, from dimes to dollars, they are very artistic and most have the purity stamped on the coin. Enjoyed the post, thank you.
I have many Mexican silver coins, but I have never seen the ones that are mixed with gold. From now on I will be looking for these. Thanks.
While not in line with what you displayed allow me to show a ring I found while metal detecting last year. It was recently inspected by an archeologist who specializes in Spanish relics. He is wondering if the ring is brass, bronze or a combination. He believes it was likely made in Vera Cruz and likely belonged to a priest. If so it was probably made this way for political protection by hiding the face inside the ring. First note the construction and how sturdily it was made. The “coin” is held in place by EIGHT PRONGS. When have you ever seen a ring with eight prongs ‘the facing coin is a replica of an Incan calendar. But looking INSIDE of the ring you will see a face. the face is Father Miguel Hildago, a Mexican priest often called The Father of Mexico. He led the revolution until his capture, torture and execution by firing squad in 1811. Truly one of my most unusual finds.
Looks like the Mayan Calendar on top of the ring. The ring appears to be old, very interesting. I like it, thanks for sharing it.
I found it in a curb strip (area between a sidewalk and the street) in the Avondale section of Jacksonville, Florida, one of the historical areas. ‘The Spanish had a string of missions and trading posts along the East Coast of Florida. They were generally a day’s march apart.
Took me a little while to find the right box but here’s a 1 peso I bought raw and had graded and a 2 peso I want to slab but just haven’t gotten to it.
