About Us!

We collect stamps and postal stationery items that are different than intended... They may be misprinted, miscut, or otherwise mishandled during the production process and are therefore special. Here are a few examples:

Stamps and postal stationery items that have production errors are called Errors, Freaks or Oddities, depending on the type of the error. A particular error is usually relatively rare, but there are many of them.

Watch this video that explains why collecting EFOs is a lot of fun!

Our Club provides members with information regarding Errors, Freaks and Oddities and is therefore called Errors, Freaks & Oddities Collectors' Club (EFOCC).

The EFOCC provides rich membership benefits, such as:
