Charles I Triangle Mm

[Cliff]

Charles I Hammered Silver Halfcrown Mm Triangle F currently on eBay. I'm aware of Triangle Mm variants (chipped, in a circle etc) but don't know of a "Triangle F".  Have asked the seller but no reply as yet. I have little knowledge of Halfcrowns, can anyone enlighten me please?

Is not F simply the seller's assessment of grade?

Looks to be heavily polished.
