Here is the mold:

I recognize that it is a plain mold in that it does not have any embossed or incused design, but does it have any other name (such as the Monarch mold is named despite being plain around the edge)? Robert Eisenstadt does not show this specific chip type in his mold index. I checked first. Also, who manufactures these chips? I notice they are used in a few English casinos for their fractional chips. Any help is appreciated.
