Card show etiquette: the unwritten rules

Always ask before picking up a card from a display case or taking a card out of its holder; boxes on the table are usually fine to flip through, but anything behind glass or in a slab stand is "ask first."

"Can I see that one?" is all it takes. The dealer will hand it to you, and that small exchange starts the conversation anyway. Never pull a raw card out of a toploader or sleeve yourself. Edges and corners are where value lives, and a dealer is right to be protective of them.

While you are looking at a dealer's card, keep it over their table and in view; walking away from the table with an unpaid card, even a step or two, makes every dealer nervous.

This is mostly about theft prevention, and nobody assumes you are a thief. Keeping cards over the table simply removes any doubt. The same goes for your own cards: do not lay your purchases or your trade binder on a dealer's display where they could be mixed in with inventory.

If a card has no sticker, ask "What are you asking for this one?" and listen to the answer before you respond with an offer of your own.

Do not open with "What's your best price?" before you even know the asking price; it reads as a lowball before any number exists. Once you hear the price, it is fine to ask if there is any flexibility, or to make a reasonable offer. If you are checking comps on your phone, say so. "Mind if I look up recent sales?" is a normal question and most dealers will wait.

Negotiating is a normal part of card shows, but offers should be reasonable and proportional; grinding a dealer on a single cheap card wastes their time and does not save you anything meaningful.

Bargain boxes are priced to move, so do not haggle over one card. If you are pulling a stack from one, it is fair to ask for a bundle price on the whole pile. On bigger cards, an offer a bit under the asking price is fine. An offer at a fraction of a reasonable price, followed by a speech about what the card is "really" worth, is not. When you agree on a price, pay it. Changing your mind after a handshake is the fastest way to burn a bridge with a dealer.

If a dealer is in the middle of a sale or trade with someone else, wait your turn; jumping in, or offering more for the card someone else is negotiating, is one of the worst things you can do at a show.

Browse their boxes while you wait, or come back later. The same goes for commenting on someone else's deal: telling a stranger "that's too much" or "I'd sell you that cheaper" in front of the dealer is rude to both of them, even if you are right.

If a table says "No trades," "Cash only" or "Please ask for help," take the sign at its word; dealers post them for reasons, and asking anyway puts them in an awkward spot.

Some dealers only buy, only sell, or only take trades on certain items. Others stop trading late in the day because they need cash to cover the table fee. If you are not sure, a quick "Are you doing any trades today?" is always fine. Pushing after a "no" is not.

Ask before photographing a dealer's cards or display, especially a whole case; some dealers are fine with it, and others do not want their inventory and prices posted online.

A quick photo of a single card you are considering, so you can think it over or check comps, is usually welcome if you ask. Be mindful of other people in the frame too, particularly kids.

When an adult trades with a child, the trade should be clearly fair to the child; taking advantage of a kid who does not know a card's value is the one thing every corner of the hobby agrees is out of bounds.

If a kid offers you a card worth far more than what they are asking for in return, tell them, and loop in their parent. Plenty of collectors go the other way and hand a kid a few extra cards after a trade. That generosity is a big part of why the next generation sticks with the hobby.

When you sell or trade a card, point out any flaws you know about, such as soft corners, creases, surface scratches or trimming, before the other person finds them.

Being upfront protects your reputation, and at a local show reputation is everything because you will see the same people next month. If you are not sure about a card's condition, say so rather than calling it "mint." The same courtesy runs the other way: if a dealer misses a flaw in your favor, mentioning it builds goodwill you will get back.

Dealers appreciate buyers who are clear about what they want, make decisions reasonably quickly, pay with exact or near-exact cash, and say thank you even when they do not buy.

They also notice the small stuff: putting cards back in the box where they came from and facing the same way, not leaning on glass cases, keeping drinks away from the table, and not blocking the front of a table while chatting with a friend. A dealer who remembers you as easy to deal with will often call you over the next time they have something on your list.
