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 
When do these mugs come out? I missed out on these big time!
The Icons came out in around 2008 and YAHs just came out last year. I am guessing you are talking about the older series!
