Another chip from my mold collection. Most of the chips from the collection were unidentified when I got them years ago. This one may be from the same place as the "JP" initial chips in The Gaming Table. It uses the same vertical line for both letters of the monogram, but this one is X-mold. At first I thought it the marking was an "S", but if you orient it that way, the rockers are different length, so I'm voting for JP. Condition is VG, with all cross-hatching and square edges.
Owl Club in Calumet City, IL is shown with a T's mold, and Whitmore Hotel in Dallas shown with HARP mold. Both operated in the 1940's and both are listed in TGT with JP and a common vertical.
