I am in Palo Alto right now, but if you can recommend some good dealers in any CA city, please do it in this thread. I want to buy some gold coins.

Well. You're lucky then. As Palo Alto is one of the few cities that have Pacific Precious Metals stores. I believe you will be able to google it and click on the map section. Though I will share the link to their online store, for you to check the prices and the bars/coins they sell https://www.pacificpreciousmetals.com/canadian-gold-coins . So give it a try and it should help you.
