I've joined forces with the hobbyDB team to create a database of every Starbucks Mug ever made! You can use hobbyDB to manage your collection and wish list, show it off, find values for your mugs, and to trade, buy and sell. We currently have four volunteers and would love to have more join the team. If you'd like to help, contact the guys at hobbyDB.
Starbucks City Mugs 
I had a Los Angeles & San Francisco Starbucks coffee mug. I acquired them about 2010. They were large. Very simple, white with one color spelling out the cities in block letters and one landmark in the same color as the letters. LA had a palm tree. SF had the GG bridge. I’ve always searched for them as mine broke in moving.
Gayle, you may be looking for Icon mugs. They were release during that time and I that was just a few years when I started collecting after my trip back from SF.
