This Mother of Pearl (MOP) chip is NOT believed to be from the Mauretania. The circular writing appears to be modern engraving applied to an older, "20" denominated MOP. It is also quite possible, that other engraving (that may have pointed to original origin) may have been removed and engraved over with the present circular printing. (reference: http://www.thechipboard.com/index.cgi/page/1/md/read/id/1275532/sbj/fake-pearl/ and http://www.thechipboard.com/index.cgi/page/1/md/read/id/1280695/sbj/modern-fakes/ )

The comment will appear with tomorrow's changes to ChipGuide.

As for pics to add to ChipGuide, as long as there are no copyright issues, they can be added.
