Nice find, and a possible match.

The one problem with attributing the chip to a country club that opened in 1959 is that we have fairly complete Burt Co. records from that time period. There are Burt Co. chips records dating to 1953, and beginning by 1956 they seem fairly complete. Between 1956 and the early 1980s there are relatively few Burt Co. manufactured crest and seal inlaid chips that are NOT recorded in the Burt ledgers and/or order cards. I've looked through the Burt ledgers from 1958 to 1965 and I can't find you chip there. Your chip might be one of the very few missing ones.

There are some possible ways you might be able to date your chip. The USPC Co. manufactured inlaid chips with 7/8th, 1, 1 1/16th, and 1 1/8th inch sized inlays. By the 1940s most are 1 1/16th inch in size. They probably stopped making any plain mold inlaid chips by 1950. The Burt Co. only created chips with inlays that 1 or 7/8th inch in size. What is the size of the inlay on your chip?

Also, is the surface smooth or textured? The textured plain mold was introduced by USPC in the early 1940s, but much more frequently used by the Burt Co. in the 1950s.
