[单项选择]When people print a stamp, any error made on a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.

A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left-fourteen One Penny Orange - Reds and twelve Two Penny Blues. Because of the Two Penny Blues’ rareness and age, collectors
