grill, 85; the six Z grill issues, 85A-85F. H grill issues, 134-144; I grill issues, 134A-141A; 143A-144A. Scott moreover lists stamps bearing the experimental J grill as minor variants (denoted by small letters) of non-grilled issues: 156e, 157c, 158e, 159b, 160a, 161c, 162a, 163a, 165c, 179c. The B grill Four stamps featuring the "B grill" pattern are known to exist, all used. All of them are of the three-cent denomination, and are numbered as Scott #82. All four stamps came from a letter sent to Prussia. The stamps were originally given a Mason, Texas cancel. Once they went to Germany (on or about March 3, 1869), they were given a German transit-date stamp. The cover was discovered in 1969 and raised controversy in the philatelic market because certain issues of the much more common "C grill" had been partially erased. This occurred during the grill roller's changing to use C grills instead of the all-over A grill. No additional "B grill" stamps have been discovered since, and one of the stamps from the cover was sold in 1993 for $85,000. Another B grill was sold again as part of the 1998 Zoellner sale (which featured the 1c Z grill) but sold for about $155,000. In 2008, the stamp was sold again, this time for over one million dollars. In Peru Although the National Banknote Company ceased to issue U. S. Stamps after being supplanted by Continental in 1873, it soon began to produce stamps for Peru, on a contract that stipulated the use of the grilling process. Grills of three different types appear on regular issue stamps of Peru produced between 1874 and 1884. One of these Peru grills displays the horizontal ridges that characterize the American Z grill, but the Peruvian version is smaller in size, measuring 9 x 14 mm. The other two grills measure, respectively, 11 x 15½ mm. and 10 x 12 mm. See also Z Grill The Benjamin Franklin Z-Grill 1c stamp 1868. References Philatelic terminology Philately of the United States
