The obverse bears oyster shell extending beyond round medal's edges. Above, BROOKGREEN / GARDENS; below, SOUTH CAROLINA

This was the 34th of the prestigious Brookgreen Gardens member medals, issued in 2006.
I was not aware that the Brookgreen medals came in variants until I acquired the copper variant at auction from the collection of Don Young. The copper variant is much rarer than the silver-plated variant, in fact I have only seen it once.
The irregularly circular medal measures 83mm x 76mm and was struck by the Medallic Art Company. No mintage is reported.
