Broadway Coin and Stamp is a San Diego Area coin shop, situated in El Cajon, California. 473 Broadway, EL Cajon CA 92021. We have been under the same owner ship since 1989, although the store has been in the same shopping center since 1982. Truth be told, although the coin and stamp industry has changed radically from when the store first opened over 3 decades ago, our desire to provide our customers with great customer service and honest and fair evaluations, has not changed. We’re still in the same shopping center, we maintain most of our original staff and we still pride ourselves on offering fair, honest prices to our customers.
