50c Orange (310). Mint
N.H., vibrant color and pristine conditionEXTREMELY FINE. AN OUTSTANDING MINT NEVER-HINGED EXAMPLE OF THE 50-CENT 1902 ISSUE.
The 1902-03 Regular Issue showed marked improvement over the Bureau's first efforts in 1894 and 1895. Perforations tend to be cleaner, and centering better, but the large plate layout and perforating method still resulted in a large number of poorly-centered stamps. Furthermore, stamps issued in choice condition were hinged by avid philatelists during the stamp collecting boom that began with the Roosevelt administration. For this reason, today's collectors have grown accustomed to paying many multiples of Scott value for Extremely Fine Mint Never-Hinged stamps. Anyone who has pursued this set can testify that the 50c is rarely encountered in such condition.
