    1863 Postage Currency Ten Cents in Billon
    Judd-326A, PR64

    1863 10C Ten Cents, Judd-326A, Pollock-394, Cassel-66, High R.6, PR64 PCGS. 24.9 grains. The normal Postage Currency pattern on obverse and reverse. However, here it is struck in billon, consisting of 60.8% copper and 39.20% silver, with a plain edge. David Cassel succinctly and accurately sums up the past (mis)understanding of the various Judd-326 variants when he wrote: "This category is totally screwy." To see just how screwy, read the four pages in his reference that deals with these pieces.

    The best way to understand this pattern is to break down 326A as billon pieces and 326B as pure copper strikings. Billon is a difficult alloy to identify since it has such a high percentage of copper, and unsurprisingly such pieces have been cataloged in the past as copper. Fortunately SEM-EDX testing has clarified the status of most known examples (this piece was tested on certificate number 60485.64/13189496. The surfaces display deep purple-blue patina with significant brightness, which we assume must come from the 39.20% silver alloy. Just the tiniest flecks of carbon can be seen in the right obverse field, preventing an even higher grade.
