Very nice collection so far. Curating such a grouping, with historic parameters that compliment the focus you're aiming for, is a worthy effort.

One thing I notice in your collection is the eclectic nature of the chips -- a number of classic different molds, including but not dominated by H&C. A number of colors for denominations -- the $5=red, etc. evolving standard hadn't taken hold yet. Each property had its own look with their inlays, as executed by the Burt Co. and inlays (most likely) drawn at Burt & lithographed at Sillcocks. And the fact that the inlays were produced in a 3- or 4-color actual spot color press run (not CMYK, as today) gives them a classic look especially under magnification.

Looks great!!
