     Any mistake made in the printing of 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. The

mistake was made more than a hundred years ago in the British colony of 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 (发行) 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 printed the words "Post Office" instead of "Post Paid" on the several hundred

stamps.

     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 ＄16,800 for it.
