For a buying visit, bring a short want list, a firm budget, and sleeves or a small card case for anything you purchase or trade. Save a few recent sold-price references for expensive targets, but compare the same set, variation, condition, and grade—not an optimistic active listing. Use the card shop directory to confirm the store’s specialty first, because hauling sports cards into a TCG-focused store or expecting deep Magic singles at a sports shop wastes everyone’s time.
For selling, organize the collection enough to separate obvious higher-value cards from bulk, but do not spend hours pricing every common. Bring government identification if local rules or the transaction size may require it, and ask ahead about payment methods, appointment requirements, and whether the buyer you need will be present. Keep valuable raw cards protected and graded cards in a box that prevents slab edges from striking each other. The selling guide explains how offers differ from retail value, while the grading guide helps decide whether a card should be submitted before a sale. Never leave a collection without a written intake record that identifies the shop and what it received.
