    1964-1965 Inco 25 Cent Test Pieces
    From the Estate of Inco Official Kenn Henderson

    1964-1965 International Nickel Company 25 Cent Test Pieces. In 1964-1965, extensive non-precious metals coin testing was done outside the Mint at different facilities, including International Nickel Company, Dupont, and Corning Glass Works. The pieces in this lot are from the estate of Kenn Henderson, an officer of Inco at the time. Andrew Pollock wrote extensive background information about these pieces in his 1994 reference United States Patterns and Related Issues, pages 443-447. We strongly recommend that bidders refer to Pollock's in-depth treatment of these little-known patterns. We have grouped the 58 pieces in this lot into three categories: 1964 Inco Large Head 25 Cent Test Pieces, 1965 Inco Small Head 25 Cent Test Pieces, and Miscellaneous "Component Pieces." Included are:
