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. The mistake was made more than a hundred years ago in the British colony Mauritius , a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer – Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius ’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally marked 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 Blue's rareness and age, collectors have paid as much as $ 16800 for it.
