Stamps printed in excessive quantities

According to an article in the Philatelic Webmaster Organization, some companies that have printed stamps on behalf of poor countries (especially in Africa) are printed in excessive quantities aimed at collecting.

Stamps are only apparently approved by local postal administrations,

The article mentions in particular

many stamps and leaflets related to minerals, from countries such as:

Chad, Comoros, Mali, Niger, Congo ,

Burundi, Guinea Rep., Guiné Bissau Rep.,

Solomon Is., S.Tome & Prince, Togolaise Rep.....
