I am talking about the Central American Hoard of 1983 which had close to 47,000 coins and most of them double eagles and most of those DEs were Saints.
Lots of early Saints from 1909-1915 and 1922. From Heritage including comments from David Akers:
"...In 1983, a large hoard of U.S. double eagles, mostly Saints, but many Liberty Heads as well, was discovered in Central America. The hoard consisted of approximately 47,000 coins, more than 90% of them uncirculated, including many thousands which graded MS64, MS65, and even higher. The hoard was purchased by Manfra, Tordella and Brookes (MTB)."
"...When Gerald Bauman of Manfra, Tordella and Brookes called me one day in 1983 to tell me about the incredible hoard of U.S. double eagles they had just acquired from Central America, he said they had large quantities of scarce, beautiful, original high quality Liberty Heads (1901-S, 1902-S, and 1905-S among others), and also a great many incredible quality Saints including such dates as 1909-S, 1910-S, 1911-S, 1914-S, 1915-S, and 1916-S. Obviously, I was impressed and interested in seeing them and purchasing as many as I could. But then Bauman let the hammer drop and said the hoard also included hundreds of seldom, if ever seen, choice uncirculated and even better examples of the 1908-D No Motto, 1908-D With Motto, 1909-D and 1922-S. Needless to say, I could not get to New York City fast enough and it turned out that everything Bauman had said about the coins was absolutely true, perhaps even understated. After spending an entire afternoon looking at representative samples of each issue, we discussed the terms under which I could buy the coins I wanted. My greatest interest was in the four rarest issues, including the 1909-D, and Bauman said that I could pick out what I wanted on an individual basis if I were willing to pay a substantial premium price and would take a minimum guaranteed quantity of each issue. After seeing the quality of the coins it was clear this was a reasonable request on Bauman's part and an easy decision on mine to agree. I still rank this as one of my greatest thrills in the coin business, both for myself personally and for the many collectors to whom I sold the coins. The 1909-D and 1922-S were the real prizes of the hoard and it is not hyperbole to note that virtually all of the choice, very choice and gem uncirculated examples of both of these issues that are available to collectors today came from the Central American hoard."
Roger's book may have more information on the hoard or he may have just quoted Akers and others. And Bowers book on hoards probably has its own commentary but I haven't bought the book yet.
