Friendly, knowledgeable, great prices! Duane or Bill are there to help you. I always seem to be there when Duane is in. Duane is a great guy, I go in once a week to visit, shoot the breeze. He educates me on coins, currency etc. The guy has taught me a lot. I usually bring in my lower grade notes, and he’s always baffled that notes can be that worn. The selection of coins is huge here. They also have a wide variety of supplies, currency, bullion, etc. Prices are always reasonable as well. It’s a great shop, and the best one in Covina! I love coming here.
