This plaque is known with a 5-pointed STAR (regular, normal-looking star) exactly positioned to the right of the B.

I know this for a fact; I held the plaque in my hand along with two exact examples as seen below. All were super-thin; at least 1/2 the thickness of usual, known MOP plaques...

Also, there are some re-surfaced MOP from CUBA which have legible engravings still remaining on at least one side; such as an "F" (French franc) and original control numbering still visible, that I am very interested in. Same goes for MOP close buttons where one side is clearly French origin.
