June 2026 — Treasure of the Month

Our Treasure of the Month for June was recently featured as Lot #364 in the Sedwick & Associates, LLC Auction #39 earlier this month. This 25.8 gram silver reale from the Spanish colonial mint at Mexico City has a broad, squarish flan with no corrosion and a bold “15” date.

It came to our attention because of its desirable provenance. This coin was sold along with an original Henry Christensen auction envelope, which pedigrees it to Real Eight Company finds of the 1960’s. There were several Christensen sales during that period, which featured silver coins from the Real Eight Company. (NOTE: The silver coins referred to in this article are also known as “reales”. This was a unit of currency used in Spain from the mid-14th century until the late 19th century. This coin came in denominations of 8, 4, 2, 1, and half reales.) Notably, the source of the coins (Real Eight Company) was never mentioned. More about that later.

Our Treasure of the Month was one of those early coins. Regrettably, the Henry Christensen auction envelope, which was sold with the coin, does not identify the auction in which this coin was sold. Why is this important? Because pedigree is everything when dealing with 1715 Fleet coins. Pedigree establishes the history of the coin and also adds value. So, we decided to do an analysis of the early Christensen sales in an effort to establish exactly which auction our Treasure of the Month was featured in. We will be focusing on eight reale coins from the Mexico City mint bearing a date of 1715, which coincides with our treasure.

The Real Eight Company made its first major recovery of silver reale coins in January 1961. This was at a Fleet wreck site located near Sebastian, which the company often referred to as the “Cabin Wreck”. The wreck site was given this name due to its proximity to a small cottage owned by Kip Wagner, President of the company. It is notable that the vast majority of silver coins from the Cabin wreck were from the Mexico City mint. The Real Eight Company continued salvaging these coins and, by 1962, had amassed thousands. That was the good news. The bad news was that they had no idea what these coins were worth on the open market. The members of the Real Eight Company would sell their silver coins to individuals on a limited basis. They would charge what they thought the coins were worth. It is surmised that they wanted to see what their coins would actually sell for at auction. If the auction prices realized were below what the members of the Company were already selling their coins for, it could negatively impact their efforts to sell coins in the future. They had to know what their coins would sell for at auction without being identified as the source. Conversely, if the auction prices were higher, then the company could raise the prices on its individual coin sales.

Early on, even before Wagner formed the Real Eight Company, he had become friends with Robert I. Nesmith, curator of Foul Anchors Archives in Rye, New York, and a man many considered to be America’s foremost authority on early Spanish colonial coins. After the Real Eight had recovered coins at the Cabin Wreck in January 1961. Wagner sent some of those coins to Nesmith for a formal opinion on their rarity and historical significance. Below is the letter that Nesmith prepared and sent to Kip Wagner on May 1, 1961:

The Real Eight Company decided to auction its coins using Henry Christensen. Robert Nesmith likely referred Kip Wagner to Henry Christensen, who was a friend of Nesmith’s. It was decided that the Real Eight Company would consign a few coins for auction in order to get an idea of the value of the coins they had found. However, it was agreed that while the coins would be identified as coming from the 1715 Fleet, the source was to remain anonymous for reasons previously stated.

On May 12, 1962, an auction took place in New York. Six Mexico City silver coins (reales) were listed for sale. They consisted of one 1712 dated eight reales, three 1715 dated eight reales, and two 1715 dated four reales. Of the three 1715 dated reales (Lots #283, 284, and 285), only one is plated (or, in plain language, pictured in the auction catalogue as Lot #283).

Prices realized.

As can be seen by the prices realized, the members of the Real Eight Company were not particularly pleased with the results of this auction, as they were selling their coins for more than the auction proceeds.

Nine months later, there was a second Christensen auction on February 8, 1963. We know that this sale contained coins found by the Real Eight Company because of a letter dated January 16, 1963, from Kip Wagner to “Bob”, who is likely Robert I. Nesmith.

In the letter, Wagner references Henry Christensen and talks of an auction on February 8, 1963. A review of the auction catalogue reveals that the Real Eight Company consigned 13 Mexico City coins and, we surmise, a group of Potosi coins as well. None of these coins was attributed to the 1715 Fleet or the Real Eight Company. But, from Wagner’s letter, no other conclusion can be reached. It is obvious where these coins came from. It is also noteworthy that there was only one 1715 dated Mexico City eight reale (Lot #51) listed in this auction. It was also plated.

The next Christensen sale featuring Fleet coins was on December 6, 1963. There were only a few Mexico City reales offered at that time. (See Below). Specifically, a 1715 dated eight reales from the Mexico City mint (Lot #1245), which was plated. These were obviously Fleet coins found by the Real Eight Company without any mention of their source.

A fourth Christensen auction was held on June 30, 1964. Again, no mention of the 1715 Fleet or the Real Eight Company. There were only five Mexico City silver reales in this auction (Lots #83 – #87), including one 1715 eight reale (Lot #86). It was also a plated coin. It should also be noted that the prices for these coins showed a considerable increase from those sold in May 1962. (See Below). This auction is also notable because it marked the first time that the Real Eight Company offered gold coins for sale. Interestingly, all of the gold coins sold for under the auction estimates!

A final Christensen sale of Real Eight Company Fleet coins was held on October 8, 1964, in Hoboken, New Jersey. This was, however, a very special sale. One hundred eighty-five gold coins were offered for sale. All Fleet-related, all from the Real Eight Company. Once again, no mention of the Real Eight Company was made. However, to ensure that all potential buyers knew the source of the coins (1715 Fleet), they named the auction “The Ubilla-Echevez Collection”. Why? Because General Don Juan Esteban de Ubilla commanded the New Spain Armada and General Don Antonio de Echevez y Zubiza commanded the Terra Firma Armada, which, when combined, formed the 1715 Fleet. Therefore, the Fleet provenance was confirmed.

As previously stated, the purpose of this review was to try to establish precisely which Christensen auction our featured treasure was associated with. So, with that said, what did our analysis here reveal?

There is very strong circumstantial evidence that our treasure of the Month was one of three 1715-dated eight reales from the first Christensen sale in 1962. This conclusion is drawn from the fact that all auctions featuring 1715-dated eight reales from the Mexico City mint were plated, with the exception of two coins, Lots #284 and #285, from the very first auction in May, 1962. This is also supported by the fact that the recent Sedwick & Associates, LLC Auction #39 offered three coins with Christensen auction envelopes consisting of Lots #362, #363, and #364.

Lot #362 from the Sedwick & Associates, LLC Auction #39.

Lot #362 has already been identified as Lot #51 of the February 8, 1963, Christensen sale. That leaves Lots #363 and #364 from Sedwick’s Auction #39 as the only two coins from all the Christensen sales without plated images, which leads to the conclusion that these two coins (including our featured treasure) are Lots #284 and #285 of the May 12, 1962, sale.

For more history regarding the May 12, 1962, Christensen auction, see our Treasure of the Month for September 2020. There, we highlight another coin from that auction, which is Lot #282. Lot #282 was a 1712 dated eight reale, which has a significant amount of history of its own. Also see our Treasure of the Month for September 2013, which features another 1715-dated eight reales from a famous auction, the October 1965 French’s sale.
