Stamp Errors

Nothing thrills philatelists more than the possibility of finding unique stamp errors. Postal systems throughout history have generated all kinds of stamp errors. Indeed, there's an entire classification of philately devoted to the studying and collection of these pieces. Called Errors, Freaks and Oddities (EFO), this subdivision of philately has mesmerized collectors for over 160 years.What defines an error? Engraving mistakes, accidental perforations down the diagonal, mis-colorations, mis-prints, inversions, and other problems can all lead to stamp errors. Of course, dispensary problems can also create infidelities in stamps. However, scratches, ear marks, and other incidental damage that takes place after the printing of a stamp don't capture the imagination nearly as much as actual postal errors do.The United States Postal Service has put out its share of error stamps, including the 1918 Inverted Jenny and the 1962 Dag Hammarskjold. Canada released a stamp in 1898 with extremely odd colorations. Known as the Canadian Christmas stamp, this strangely beautiful piece has captured the imaginations of generations of philatelists.Before rushing off to the auctioneer with your newly discovered rare stamp error, you want to authenticate any finds. Modern stamps generally include anti-counterfeiting measures. For instance, Canada's 1997 eight dollar Grizzly Bear stamp features numerous watermarks, including the number ''8'' printed all over the stamp. If and when you do find an error, be sure to preserve it quickly and carefully.
