Contemporary Circulating Counterfeit Vs. War Of Independence Mother Coin Prototype

A recent pickup at the NYITL does pose an interesting comparison for this coin as either being a currently UNIQUE GNL variety (specifically: GNL# 1810-O:F/R: Lima JP-002 based on my current ongoing database of new GNL varieties) or a WOI prototype? Its metrology is 38.55 mm and 24.28 grams. I have XRF tested Chihuahua cast silver regal issues KM# 123 for the 1811-1813 types and some weights are outside and below 26 grams into 24 and 25 grams range and some are slightly debased silver with copper. This was published in a previous MNA Journal but removed several years later due to all WOI papers being removed from the MNA Journal based on new Max Keech discoveries of countermark or more accurately as suggested by Max Keech as mint stamps and his different meanings and origins as compared to the Pradeau bible of WOI. Interestingly some rare 1810 Ca (mintmark) RP (Assayer) types have been recorded. This particular piece has a different head style than seen on all previous Chihuahua Cast regals (KM#128) since at this time all Chihuahua Cast Silver pieces produced by the Royalists in the Mexican War of Independence used Mexico City coins as MOTHER COINS based on my research. Mother coins being a term used as regal issue 8R coins were used to make the cast molds and then after making the molds then changing the mintmarks to Ca and assayer to RP in the actual molds produced by the regal coin always being from Mexico City. See this interesting Chihuahua prototype for Chihuahua using an earlier Charles IV dated 1805 instead of Ferdinand VII sold at Stacks awhile back to give you a better understanding of what a WOI prototype is in this realm of collecting: https://auctions.stacksbowers.com/l...ced-in-1810. The edge on this GNL CCC8R coin is crude and it seems each circle and rectangle or square (whatever is your viewpoint) was hand punched into the edge. So no Treasury (T) or Pillar of Hercules mint stamps as per Max Keech, no mint changed to Ca and assayer change to RP but XRF results yield a ~80% Ag issue similar in some assays to Chihuahua Silver Casts (KM#128). Additionally, the end ribbons being as KM#106.2 for the prototype matching a Peruvian Mint 1810 regal 8R in KM. Still its high silver content and cast appearance does possibly a suggest a Mexican WOI Mother Coin Prototype? Why the high silver? Still a longshot - I agree - but a piece suggesting a link to the Chihuahua pieces IMO. An interesting discussion piece nevertheless. John Lorenzo, Numismatist, USA.
