Errors
Errors are the blue bloods of EFO collecting. Because many are listed in catalogs, they are sought after and generally trade at higher prices than freaks or oddities. The price for any given item depends upon its popularity and the number of examples that are known - in other words, supply and demand. Some are plentiful. An example is the imperforate-between 1 1/2¢ St. Louis precancel of the 1938 Presidential series. A pair can run as little as $10. But the Inverted Jenny, of which only only 100 copies were produced, can cost 10,000 times that. The most reliable information on pricing is from catalog listings and from current auction realizations. It should also be noted that where money is to be made, there are those who will manipulate the product to cash in on it. Buyers are well-advised to require or obtain a certificate of authenticity on expensive material from a recognized stamp expertizing organization before concluding a deal.
The imperforate between Scott 805b 1 1/2¢ St. Louis precancel of the 1938 Presidential series is an example of a relatively inexpensive error.
