Gretsch Aniversery Edition

I just bought a Gretsch Diamond Aniversery model but can't determine the year. I've looked in almost every book that I could find but it didn't have it in. It is an Elec acoustic with one pickup, cream color, and the serial number is G01960 If anyone could just give me a resource that I could go to to find to the year that would be great. Guitarman14
