    1869 'Koulz's Alloy' Dime
    Judd-717A, PR65
    Copper / Nickel Composition

    1869 10C Ten Cents, Judd-717A, Pollock-798, Cassel-24, High R.7, PR65 NGC. 45.94 grains. The undated obverse is similar to the regular issue and was used to strike the Postage Currency patterns in 1863, as seen by the broken top of the first S in STATES. The reverse features SIL. / NIC. / COP. in the center, followed by a straight line, the date in the exergue below and in a smaller font. Allegedly struck in the unworkable Koulz's alloy with a reeded edge. SEM-EDX testing conducted by Ledoux & Company Certificate number 235641-018 actually showed this piece to be struck in 74.5% copper, 24.9% nickel, 0.33% iron, and 0.27% cobalt. Two of the three elements in Koulz's alloy (or more precisely Montchal Roulz's alloy) are present in this piece, but no silver was found. This is a brightly mirrored proof whose reflectivity greatly enhances the oil-slick patina seen over each side. High-point definition is lacking on the hair and breasts of Liberty, not surprising considering the hardness of the alloy this piece was struck in. Numerous flyspecks of carbon are scattered over each side, but there are no obvious or detracting contact marks.
