The 1870 90c National Ungrilled Issue, Scott 155, is somewhat overshadowed by its grilled counterpart, Scott 144. Collectors are also misled by the availability of Scott 166, the 90c 1873 Continental. Although the difference in shades is distinct, collectors have a tendency to confuse the two and under-rate the 1870 National printing. Only a few original-gum examples of Scott 155 have the centering, color and freshness of the stamp offered here.
