11) gilt-brass "Central American Independence" Reverse Trial 1000 Colones PR67 - KM-Unl.
Italcambio mint. A fascinating set, sure to be of the highest interest to collectors of the Costa Rican series. Absent from the Whittier, Pura Vida, and Mayer collections, Manuel Chacon--curator of the Costa Rican Central Museum in San Jose--reports knowing of only three such sets in total, two of which reside in the Museum's own holdings. Closely following the issued set produced to commemorate the 150th Anniversary of Central American Independence, each of the trials seen here displays a small rectangular stamp containing the letters MET. struck over the area that would usually carry the set's serial number. Equally interesting is the presence on the 20 and 25 Colones of two unusual patches in the silvered surfaces, which show clear hairlining. Judging from the shape of the areas and the abrupt end of the hairlines outside of them, it seems likely that the planchets were burnished prior to silvering, with the silver layer being particularly uneven or weak in these areas. For the sake of accuracy, we would also note that the "reverse" of the 25 Colones shows a wandering scratch, though it is unclear if this occurred during the production process. According to our research, this is the first occurrence of such a set at auction, and likely represents the sole representative in private hands, making it an opportunity not to be missed!
