The coin show environment, as exciting as it can be, can also be intimidating to a first time coin show attendee. Even some long-time coin show fans regularly break the rules of etiquette and courtesy at coin shows, by doing things that aren't "dealer friendly." The most important rule that anybody can follow at a coin show is this:
Put Yourself in the Coin Show Dealer's PlaceCoin show dealers often bring their best merchandise to coin shows, since they will have an opportunity to interact with other dealers and lots of customers who might be looking to buy the coins they are trying to sell. Since the offerings at coin shows usually represent the very best stock that dealers have, they are understandably more nervous about potential losses to that merchandise. Therefore, one of the most important things you, as a customer, must always keep in mind is making the dealer comfortable that you are not out to pilfer his prized possessions.
Coin Show Shopping With Purses and BagsKeep bags, purses, satchels, and other containers away from the table. If you are standing at a coin show dealer's table and looking through boxes or trays of coins, keep your bags to your back side, either on your shoulder swung around back, or way up on your arms, so your hands and lower arms are free and open to view. The point is that you want the dealer to feel comfortable that you are not slipping coins into your purse or satchel.
If you sit down at the coin dealer's table, never put your purse or bags in your lap! Always place them on the back of your chair, if possible, or on the floor beneath your chair. Avoid putting bags on the floor between your legs, because the "peek and drop" is probably one of the most common ways that dealers lose coins at coin shows. (The thief takes the coin in hand, and at an opportune moment lets it drop down into his lap or between his legs into his bag.) Always put yourself in the dealer's place, and try to see how you would perceive someone's actions if you were at his side of the table.
Coin Show Cherrypicking CourtesyAt coin shows, be cognizant of where you take coins from, especially from fixed-price boxes. Sometimes coin show dealers put out boxes or trays of coins that have a fixed price on them. If you shop from these boxes, only look at one price group at a time, and then set those picks aside or have the dealer bag them up for you, so that you don't get merchandise from different priced boxes mixed up.
Always pay attention to where you took a coin from, so that you can be sure to replace it in the proper box or tray if you don't end up buying it. Not only is this just common courtesy to the dealer, but you save future customers some aggravation, too. There's nothing more disheartening than finding a $40 coin in the $5 pick box, only to learn that it should have been in the $40 box and some previous customer had misplaced it. This puts both the dealer and the customer an awkward position! So think about this when you buy from pick boxes.
Bookworms and Checklists at Coin ShowsKeep your books and checklists away from the coins. Coin show dealers usually aren't too thrilled to see customers pulling out books and checklists while they shop for coins. If you're a "checklister" type, keep the dealer's perspective in mind. Books and papers are really good places to slip a coin or two, and many dealers have lost coins this way, so always bring the minimum amount of paper onto the table. Keep the coins you pull out very separate from your reference material; don't let any coins get near your paper stuff. Don't keep your papers in your lap, though, because nothing looks more suspicious to a coin show dealer than a customer who is constantly bringing his hands from the boxes and coin trays down into his lap. Keep the papers on the table, but off to one side.
If the dealer's table gets busy, and you know you're likely to be a small customer for him, step away for a few minutes so others can have a look and move on. If you've pulled some coins you want to buy, ask the dealer to hold onto them for you for a bit. Never step away from a coin show dealer's table with unpaid for coins, even for a moment! This can get you thrown out of a coin show if the dealer thinks you were trying to steal his coins. As in all things, communication is key.
