There was a Turf Club in Seattle (3rd & Union) from mid 50s thru 1974. They had non-denominational DIASQR mold chips in Blue, Black, Off White & Yellow with the gold hot stamp "TSC". There also was a white DIASQR with the GHS "Turf" & a horseshoe and a brown TRIANGLE with the GHS "Turf" but no horseshoe.
