~~~ this has always been known as a K with a small D above the K.

Though I only know of these two pieces; which the 20F chips have turned up mostly in the Savoie, I'm searching for other denominations.m

The 20F chips are also found in several thicknesses.

I will update ChipGuide... Not sure if my submissions are being received and that's why I post here too.
