to ChipGuide for that scan...

"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."

Is this wording acceptable?

John, do you agree with the comment?

Thanks,

Jim
