Significant examples:
PCGS Proof-65 (illustrated above).  Ex - Ira & Larry Goldberg Coins & Collectibles, Inc.'s "The California Sale", October 2-3, 2000, Lot 590, where it was described (in part) as follows:  "Postage currency, nickel, reeded edge. This is one of the very rare examples of emergency issues during the Civil War. The obverse depicts a shield with two arrows crossed behind, and an inverted laurel wreath above suspended by a ring. On the obverse, the inscription reads EXCHANGED FOR U.S. NOTES. The reverse is very plain, it reads POSTAGE CURRENCY, ACT JULY 1862, with 10 CENTS 1863 at the center. This coin is well struck, with reflective fields and satiny devices. A few very minute tick marks can be seen, as well as some trivial toning flecks.  One of only two graded by NGC and PCGS, both the same grade, and possibly the same coin as it may be been submitted to each for their respective opinions. Whatever the case, this is an extremely rare pattern issue and it is amazing that it has survived in gem condition all these years.  Probably the DiBello coin (Stack's 1970)."
