The article is done and was sent to the Mexican Numsmatic Society.

For Chihuahua pieces that were debased or of a Sheffield character its being suggested these are contemporary counterfeits of the period.

For Chihuahua casts of 1811 some come without regal edges but are 90% silver with perfect Pt/Au ratios. This SUGGEST there may have been a lag period before the 1811 pieces were applied with a regal edge. So an 1811 Plain Edge piece may not suggest contemporary counterfeit.


Preliminary evidence with the LVO pieces seem they are all probable Plain Edge and have possibly? determined most seem to have been produced with improper alloy mixing as many are discolored and do not have good silver appearances, etc. - it seems on some piece the copper may have come to the surface on a few pieces - that DOS MUNDOS November 2012 Stacks piece they called a contemporary that was countermarked indicated perfect Ag,Pt & Au readings ... this anlysis is continuing ... for a seperate paper. I have no idea why the Stacks catalouger called that LVO piece contemporary in the Stacks Novemeber 2012 sale.

Actually it was sent to the Mexican Numismatic Association (not the MNS). As a member you should see the article in the next journal publication which is quarterly.

See my article on the Kleeberg Counterfeit 2 Reales Off-Metal pieces (UPDATED from the previous ANS-COAC work) in the MNA Library.

The new book on the CC8R's is similar in terms of the types of off-metals being identified but in the CC2R's german silver is much more common. Still a rare alloy overall but with CC8R you may have 6-8 varieities known of the Class 1 varieities in the new upcoming GNL book in GS whereas in the CC2R series its about 10% of the the currently known (87) varieties. With Kleebergs there are no Class 1-4's. To be a Kleeberg variety its Class 1 or your not classified with a K-designation. Debased silver CC2R's are non-Kleeberg's. In some ways we reached the same conclusion ten years apart. If a CC2R is debased silver its not of the off-metal counterfeit Kleeberg contemporary counterfeit family, possibly from China, Great Britain, USA or else where and therefore made possibly later and not contemporary (i.e., 1771-1822? whenever FVII reign ended) UNLIKE the contemporary counterfeit of the period off-metals as in brass, bronze, copper, silvered brass, silvered copper, tin, german silver, etc.. Since German Silver was probably not available until after 1830 in the Americas it is an exception in that this alloy is considered made with the other off-metal alloys or that SOME of these counterfeits were made BEYOND the end of the regal period ... since we don't know which ones were made in the regal period ... they are all defaulted as contemporary pieces. Did some of the GS pieces come from China, Britain or made in the U.S.? We may never know. Kleeberg has shown that CC2R's circulated up until the Civil War or until 1857 or until Coinage Act of 1857 that forbid foreign coins as currency in the U.S..

wonghinghi : it's 20 USD per year :)

Or ... well if you are not that bad, you can get everything for free :P (took me about a minute to get all the docs and about a minute more for the site password ...)
(I paid my subscription, will be glad to help fix that if asked)

Here is the site : http://usmex.org/

colonialjohn : I saw many interesting articles, including that one. I'll need some time to read those, I'm quite busy lately.
But yours was one of the first I downloaded for later reading - it looks very extensive ! :D

Thank you your information MathieuMa, but I prefer to pay officially and get the information formally. Can you provide a site for registration?

wonghinghi : I never mentioned giving out those details, and I paid myself ;)
Just go to their site - http://usmex.org/ - and in the top bar go to Membership -> pay electronically
You'll have to wait a bit so someone takes care of giving you the access (that's where I didn't had to wait - I'll tell them once I get it)

Not sure what they will do with the recent cast 8R Chihuahua article - put it in the next journal or in the library - I tried to keep it to two pages which is the suggested maximum length for the MNA quarterly Journal.

Its not the ANA - it may take a week. You should receive a password and be able to access the on-line library.
