Unfortunately, many coins are struck by mints which prefer to remain anonymous - they do not use mint marks, and even on coins that come with certificates of authenticity, these carefully avoid mentioning a manufacturer (thus making them basically useless).
We try to find out which mint makes which coins and coin ranges, but it is not always possible. We would appreciate help with the identification of mints that made coins listed by us under "unknown mint", if any of the site's visitors is in possession of such information. |
