  The Last Gold Cobs from the Lima Mint:

trying to explain the anomalous issue

 of 1750 Lima four Escudos


L62. Peru, LIMA 1750 R  four escudos.  A beautifully struck, heavily coraled, mint state media onza recovered from the wreck of Nuestra Senora de la Luz (1752). An exceptionally well struck 4 escudos pillar side is paired with a bold 8 escudos cross side.


Before the discovery of "Our Lady of Light" in 1993, the 1750 Lima four escudos was not known to exist. The recovery from the La Luz proved a 1750 four escudos mintage occurred, but revealed that something totally unexpected and unprecedented had happened in the last days of Lima's gold cob coinage. It is now clear that the largest issue ever of four escudos from the Lima mint (1696-1750) occurred in 1750, and in fact mostly in the last month (December) of 1750, and in a completely unplanned fashion.


No explanation of this remarkable mintage is yet forthcoming. All we know is that such an exceptional mintage of four escudos never occurred before or after 1750  at the Lima mint. The four escudos was always the rarest denomination at Lima, both for cobs and the milled portrait issues that began in 1751. For the entire post-Fleet era, 1715-1749, only 4 or 5 Lima four escudos are known, reflecting no mintage at all in most years or only a very exiguous mintage that has vanished. Portrait Lima four escudos are almost as rare for years after 1750. All Lima four escudos are rare coins! But here is what we do know about the remarkable mintage of 1750.



The Uruguayan salvors of La Luz found fifty 1750 Lima four escudos. They auctioned most of these coins in a 1993 New York Sotheby's  sale. Our coin was lot 548 and realized $6350 nineteen years ago.  The salvors of the La Luz were numismatists and quickly noticed something strange about the 1750 fours. First of all, there were seven different cross dies in use (one or two would be normal). Secondly, five of the seven dies were not four escudos dies at all. They were 8 escudos or even 2 escudos dies. The vast majority of the 1750 four escudos mintage was not struck from four escudos dies! This was no mint error or mistake. Clearly the coiners at Lima in 1750 had encountered a problem: a large mintage was unexpectedly required (late in the year) and the two normal Lima cross dies were already exhausted. What to do? No new cob dies could be ordered because the cob coinage was now discontinued in favor of milled portrait issues. The coiners had to make do with whatever was on hand, so they carried on striking a substantial four escudos coinage with 8 and 2 escudos dies. Nothing like this had ever happened at Lima, or at any other Spanish Colonial mint for that matter. It was illegal, but necessity made its own law. (The same problem occurred to a lesser extent with the 1750 eight escudos mintage, where the coiners had to mule a worn, retired 1749 pillar die with a 1750 cross die to complete the onza mintage.)




The workmanship of the final Lima gold cob dies under assayer Rodriquez (R) never approaches the fine quality of the Hurtado's (H) or Megarejo's (M) Fleet-era coinage. Designs features like the lions and castles were often unusually crude in the last years of Lima and carelessly punched into the dies. That said, Rodriquez had clearly made some effort with the dies for the last year of cob coinage. This 1750 four is struck from a normal 4 escudos pillar die and an eight escudos cross die. Seven 1750 fours of this variety were found. See page 111 of the Sotheby's catalogue.


The December 1750 coinage using  8 escudos and 2 or 4 escudos dies almost always shows weak and worn features. The lions and castles in particular often lack any detail. . This coin is the best of that small (7) group. It is  mint state and beautifully centered. A better specimen of this last gold cob from Lima  will be very expensive.



We need to briefly explain why NGC has graded a choice mint state 4 escudos as an AU.  The label above from NGC tells the tale. NGC currently believes that heavily coraled, original ocean coins need to be "conserved" to earn a mint state grading. Indeed, "conserving" an ocean gold coin will give it brighter surfaces--but at the expense of removing the 260 year old coral matrix that testifies to the shipwreck origins of the coin. We strongly recommend that collectors declining "conserving" their shipwrecks coins and removing irreplacable original deposits.


It is hoped that on-going archival research will solve the mystery of the 1750 Lima four escudos coinage. A researcher tells me that there is a suspicion that an re-coinage of underweight/illegible 1746-49 escudos suddenly was mandated. If so, this could hint at an unprecedented problem or scandal at the Lima mint. Lima never had problems like Potosi. Whatever the cause, the exceptional final  mintage of 1750 is already a special event in the history of El Peru's gold coinage.
