1964 DuPont Quarter Pattern Undated (ca. 1964) Pollock-5391 This metallurgical trial was produced by DuPont in 1964. They were one of several companies the U.S. Mint commissioned to find a suitable alloy replacement for silver. The obverse is of Benjamin Franklin and the reverse shows the DuPont emblem with the inscription "This token made from explosion bonded "Detaclad." Detaclad is a patented process for laminating 75% copper, 25% nickel to a copper core. From my research I found the mintage was 500 with the pieces made for presentation to U.S. officials. The current NGC graded population is 7 across all categories.
I will be sending it in for grading to NGC but I have no doubts about its authenticity. The seller I purchased it from has very reputable feedback (40k+).
