San Diego. "Sidepot" is correct, I believe the chips are made in Mexico (unless shipped over from China). Here's a website: http://www.buypokerchips.com/v/poker-chips-media.htm

BuyPokerChips.com was the former name of Sidepot. Now, scroll down past all the good advertising stuff and you'll find a $100 chip of very similar design with those palm fronds, Archtype Line. Come in various colors and denominations and a few other designs. Mystery solved, without need for Sherlock and Doc Watson.
