We have coin shows on the 7th and every Sunday after that in November.
As a general rule I've found prices at these shows are much better than larger coin shows. These are usually from 40 dealers to about 100. No parking fees, no admittance fees, usually free copies of coin magazines if you get there early. Many dealers are the same ones at each show so you get to know them. Some will hunt for certain coins for you and for decent prices once they get to know you.
If you go to shows many times, attempt to get to know the dealers. Talk to them about anything so they get to know you. You do not have to buy something from them all the time, just let them know who you are. Don't worry about talking to dealers. If a dealer doesn't want to talk to you, they'll let you know. Actually I've found some are difficult to get away from if you are a decent conversationalist.
