So far it's only the bicolor blue/natural MOP "20" and the "5" Bone that were sent to Cuba and, most likely after 1911.

The "20" with the red engraving were never found there and, those that were found were found before Castro.

The example seen above is a "100" (mine, and came from Europe over 25- years ago) and only here to show the exact monogram.

What inventory existed after 1911 and where it went is unknown to me but, "I think" the red engraved "20" jetons were newly made after 1911 and sold with the obsolete inventory which, is not important since I am talking Cuba, only, here.

The information told to us years ago about the MOP possibly being used in CUBA could not have been more accurate at the time and had to have been known for many years, prior.
