I am raising this topic once again to provide an updated report on my progress to date and to correct a few of my initial beliefs which need to be modified.
The actual number of records that NGC allows on a look-up averages 7 per hour. Not a lot but it has proven adequate to proceed.
At the present time, I have identified 36 individual invoices that included silver and copper coins. I have also identified 12 invoices that list only gold coins. I have not bothered collecting detailed data on the gold coins since there are published records of the gold recovered.
The 36 invoices are of two distinctly different types. The lowest and highest number invoices (which I presume to represent the initial and final submissions) are the most random in nature. These are also of varying length. There are 11 invoice numbers in that group - the 8 lowest and the three highest.
The 8 lowest invoice numbers fall between 1212989 and 1215094. They vary in the number of coins per invoice from a low of 30 to a high of 140. In all these 8 invoices include 716 coins and most of the World Crowns.
The last three invoices 3297121, 3371377 and 3455823 range from a low of 14 coins to a high of 119 coins (148 total). These are a mixed bag and include the majority of coins returned to the salvors by NGC as "Unsuitable for encapsulation".
The easiest group is the second one, a group of 25 invoices numbered between 1970084 and 1975083. These invoices include 50 coins per invoice and the submissions are alpha-numerically sequenced by country, denomination and date. There are 1250 coins in this group.
So the grand total that I have looked up on NGC is 2115 coins in invoice order. I did a second hand counted tally done by country and denomination that ended up with 2116 entries so I have a failure to check of ONE coin. Not too bad and statistically insignificant.
Most of the data gathered confirms what I suspected to find but some individual statistics were very surprising. I am not sure how much of this data will be of general interest so I will start with overall statistics and then move into more detail as interest dictates.
The only copper coins listed were
US Large Cents. Not surprisingly there were only 17 cents the rest were all silver coins 1199 in total. Here is a list of the numbers of
US coins by denomination:
US Cents 17 1.07%
US
Half Dimes 25 1.58%
US Dimes 99 6.25%
US Quarters 111 7.01%
US Halves 1,330 83.97%
US Dollars 2 0.13%
US coins total 1,584
So about 84% of
US coins in the group are Half Dollars.
World coins break down differently. The list is by comparable value based on the Reales system.
Copper cents 0 0.00%
Half Reales 0 0.00%
Reales 31 5.82%
Two Reales 96 18.05%
Four Reales 17 3.20%
Crown (8R) 388 72.93%
World Coins Total 532
Crowns predominate world coins with almost 73% of total.
When I read the auction releases and info about the wreck in publications I expected to find a wider distribution of world coins present. Out of the 532 coins 494 are Spanish Colonial or former Spanish American colonies. 450 are actually Mexican.
There are only 3 World coins of the 2 reales size - two English Shillings and a single fractional Taler. There are only 35 world Crowns and most of these are French 5 Francs.
As I suspected from Riddell's work Mexican coinage predominated. Of the dollar coins found only 1/2 of one percent (2) were US and 9% (35) were World crowns other than Mexican. Mexican crowns were 91% of the coins in circulation.
I still face the same problem of not having seen the encapsulated coins. Of all the coins encapsulated I have managed to see only 102. Of those at least 3 are in fact counterfeit and one is mislabeled Guanajuato when the mint is actually Chihuahua. There are two coins dated AFTER the ship sank - an 1847 Mexican 8R and an 1857 French 5 Franc. The last two are impossible since the ship sank in 1846.
The most common coin recovered from the wreck and encapsulated is the 1844-O Half Dollar (230) and the second most common the 1845-O Half Dollar (223).
I was somewhat surprised that the coins were dated as closely to the wreck as they were. There were as many
US coins dated in the three years 1846, 1845 and 1844 as all dates before that. I conclude that when coins circulated as specie (full intrinsic value) and wear caused them to stop circulating quickly, that older coins were even less common than the silver change I grew up with in the 1950s.
The two US dollar coins were dated 1795 and 1798 both Heraldic types. I wonder if these were circulating coins or pocket pieces - I have the same suspicion about the 17 large cents. Of the 17 one cent coins 6 were dated 1845
There was one rare US coin an 1815/2 But Half Dollar and a fairly rare Mexican Durango Hookneck 8R from 1824. There were far more New Orleans mint issues among
US coins than Philadelphia - not surprising since the ship ran from Galveston, Texas to New Orleans, Louisiana.
Since I know there were at least 3 counterfeits within the 102 coins I have seen a 3% counterfeit rate is supported. However, I view the sample of 102 coins as too low to be completely accurate. So given that there were 450 Mexican 8Rs recovered I would expect that no fewer than 10 other counterfeit Mexican 8Rs may be in NGC holders.
If anyone can help by locating other invoice numbers or any other data on this wreck I would be very interested.
I can also extract many other details if anyone is interested.
