Errors
With the printing of such a large number of stamps year after year by many different states and printing agencies, errors do occur, but are seldom found. A few federal stamps are known to exist with major errors, but only a few, namely on the 1934, 1986, 1990, 1991 1993, and 2003 issues.
Stamps without perforations, with missing or incorrect color, missing or inverted writing on the reverse are all major errors. Smaller flaws, such as color shifts, misplaced perforations, hickeys (or donuts) and other such anomalies are termed freaks, rather than errors. These, too, are collectible and have value, but they do not command the same attention as major errors. Major errors are extremely rare and exist in small numbers. All errors and freaks on duck stamps are very desirable and add a great deal of interest and value to a collection.
