The recent posts from
jgenn,
Numister and
NumisRob provide a tailor made oportunity to classify fakes into "Counterfeit" or "Numismatic Forgery" categories.
NumisRob Your fake pound coin is the most simple to categorize. It is a
Contemporary Circulating Counterfeit. It was produced while the coin being copied was still in circulation. It was made to defraud merchants and not coin collectors. It has rather obvious errors that the vast majority of UK citizens would readily miss if they received the coin in circulation. Numismatists should have no problem with these blundered fantasy issues. The profit for the forger involved, derives from the difference between the cost to manufacture the fake and the value when passed. This coin is actually a Token, meaning the value is established by law (fiat value) and the worth in commerce has nothing to do with the intrinsic value of the metal. It is quite possible, even likely, that the coin cost the forger more to produce than a genuine coin costs
The Royal Mint. However, the seigniorage (definition: profit made by a government by issuing currency, especially the difference between the face value of coins and their production costs.) is adequate in both cases so that the forger's profit is simply a smaller fraction of the mint seigniorage. But it is enough.
Numister Your coin is a bit harder to categorize but as I see it the clues are there. Hint: the edge is the decoding factor. Does anyone see what is amiss and how that would effect the age o this coin? I will make a longer reply about the type once people hazard guesses.
jgenn The 1756 Mo MM is clearly the most difficult to classify by age of these three coins. In cases like this, there is often a disagreement as to how to interpret what we know about the coin.
I will not paraphrase John Lozenzo's opinion about the coin because I do not want to be accused of setting up a straw man. Here is my take away from what I see.
1. A 1756 Pillar Dollar circulated until the early 1800s very freely, however, due to normal wear, examples of the grade seen here were at best rare in general circulation before 1830. The coin was virtually unknown in circulation in 1845 and by that date even Portrait 8Rs were scarce to rare in high grades. The most probable interval for counterfeit production fitting the definition of CCC is the period ending within 15-20 years of the end of the Pillar age (roughly 1786 - 1791). This is because counterfeiters making coins for general circulation target very common coins not coins that are rarely seen. Coins rarely seen attract unwanted attention something counterfeiters want to avoid at all costs. This position can be disputed of course, however UK mint studies of wear and life expectancy of "dollar" sized coins in the 1790s as well as US mint survival studies of world coinage must be considered when making a counter argument.
2. Before 1830, there were few (actually only 2) technologies available to counterfeiters to produce their coins - the first was striking from dies and the second was casting. Cast coins were made from "sand cast" molds or Plaster of Paris molds in the 1820s at the best. These molds are crude. Having examined hundreds of examples of the period I will state that categorically this is not a contemporary cast from any mold that could have been made before electro-typing. The question is what is this coin? Is the presence of "Flow lines" adequate to prove a coin was struck? Could this be a modern cast copy that retained flow lines from the host or is it a strike on a very poor cast planchet?
3. The coin's designs are actually correct for Mexico City including the individual letters and numerals. This perfection in counterfeit dies is simply not seen in period fakes at least not in my experience. It also raises a question in my mind of was it possible for any forger (prior to 1830) to create a pair of dies to strike such a coin? The answer I gave in my book was a definite NO. The British could not do it and resorted to making false dies by engraving individual master punches. They did a great job however comparisons with genuine Mexico City designs reveals tiny differences in EVERY example. I would add as a more or less rhetorical question "Why did the counterfeiter spend the time to create essentially perfect face dies but do such an absolutely lousy job on the edge?"
4. The edge in this case was clearly applied after the face designs were in place - namely after the coin itself existed - the edge is weakly applied - very shallow and the design itself is a well known design used by forgers active in China recently. I base this on personal observations of numerous forgeries which of course can be challanged and I welcome any information that would overturn my conclusions.
5. The XRF test indicates a coin that is predominatly copper 83% and silver 16% with a bit over 1% of trace contaminants. Gold is not noted in the XRF test but with silver at only 16% the expected trace would be about 0.04% gold to be real. That is well within the predicted range of variation. So that is a push. It is clearly not a Sheffield plate so it must be a solid alloy. Such an alloy would have a density of roughly 9.3 not 10.3. This means the coin must be significantly thicker than normal to raise the weight - So would the coin fit through the standard slot found in a
Counterfeit Detection scale of the contemporary era? Would any bank of the time accept the edge as correct?
6. The XRF test in my opinion does not demonstrate age at all. It could just as easily be a test of a modern Chinese forgery.
My considered opinion is that this coin is a
Numismatic Forgery and not a Contemporary Circulating Counterfeit. I suspect the note written by J. Lorenzo was written before extensive discussions we had during the writing of the book "Counterfeit Portrait Eight-Reales". I believe the coin is a centrifugal cast copy made from plastic molds of a genuine 8 reales. The surface of the coin is flawed by retained air in the final product. I believe it was edged after it was cast and that the origin was definitely China sometime after 1999 and as recently as 2014.
