Tucson has a spring show every year, thats 100 tables plus. There are 3 " Bick" shows a year, google Israel Bick coin shows, there is an annual Janurary show for the Mesa Coin Club, and there are monthly Scottsdale shows......There are Northwest Phoenix shows every 6 weeks, but mostly cards and sports The Coin Club show far and away is the best
The Tucson show mentioned by Jack is in mid- January and is a great show - it draws dealers from all over the country and is very well done and usually well attended.
