Thought I answered this prio.

Two addresses in San Diego, CA

4701 and 4744 El Cajoh Boulevard
4701 address opened 1976 and closed and moved 1983
4744 address opened 1983 and closed 1990's

I don't know the location your 25¢ chip was used but am interested if available.

Wishing you enough,
Dick Staeffler R-3828
