~~~ the monogram from many establishments differ on metalliques and nacre... and even follow with being different with each other on documents, letterheads, casino gate and façade -- and more, such as a completely different monogram on both obverse and reverse... which causes the problem we see on the Internet in calling a chip incorrectly. Luckily we can prevent that from happening on ChipGuide by study, study, study...

My 20f is still a Unidentified MOP... for now... unless we find something with text and monogram in the same breath.
