Hi I’m new at roockhounding but found this what I believe is a chert geode containing quartz?? should I try to flatten and polish the front around the “hole”? Are these common? (Can’t really find chert geodes anywhere on the web it seems).

Welcome to the forum.
Chert is just a sub-category of jasper, which along with agates and common chalcedony are all chalcedonies that are cryptocrystalline to microcrystalline quartz.

I think it would look good with a polished face.

Its easier to face polish one of these stones because you can concentrate on the edge/rim with no need to polish the crystaline interior. Hence essentially you are going to dome the outer rim, the equivalent of doing a much smaller stone in terms of getting to the exposed surface to get rid of scratches. By carefully holding the stone so that only one section of the rim is in contact with the wheel at a time and doing all the necessary rotations to avoid producing scratches all in the same direction. This is all very hard to describe in words, but think of it as doming the edge/rim instead of the entire exposed area.

I'd just whack it on my flat lap, it would have a flat face, but a domed rim sounds like a cool idea.
