KM-Pn15. Struck in brass, this piece was produced in unknown quantity for use in a mint set issued by the Paris Mint. Krause incorrectly attributes them as patterns, likely because of their off-metal strike. Very well struck, this example displays just a touch of friction and spotting, but the warm surfaces are never anything besides attractive. The SUPREMELY RARE nature of this piece makes it likely to be hotly contested, as examples from this set do not surface often.
