San Francisco International Numismatic Bourse

The San Francisco International Numismatic Bourse is the San Francisco International Coin Show, and Portsmouth Square Company is the organizer. Scott Griffin of Griffin Coins publishes the date on the company coin-show page, which is the organizer site rather than a third-party dealer calendar.

The organizer lists one next San Francisco date: Saturday, December 5, 2026, from 10:00 a.m. to 5:00 p.m. The venue is the DoubleTree Hotel SF Airport, 275 S. Airport Blvd., South San Francisco, CA 94080. The page says the hotel shares a parking lot with the South San Francisco Conference Center and is about five minutes from San Francisco International Airport. The hotel phone listed there is 650-873-3550.

Admission is $8. A flyer, postcard, email printout, or a printout of the organizer page takes $2 off. World, ancient, and U.S. coins, currency, and other collectibles are bought and sold.

Dealers named for this edition include Musa Numismatic Art, Leu Numismatik USA, Ken Dorney, Multnomah Coins, Classical Numismatics Group, Griffin Coins, Herakles Numismatics, David Showers, Kurt Herrmann Rare Coins, Ron Galileo, and ANACS Grading Service.
