I agree with everything cknack said. A neat and priced display is important imo. If I’m walking a show and see a table with cards not priced, I usually just take a quick look and keep walking. Having a good mix of cards it important. I usually have $1, $2 and $3-10 boxes along with my showcase cards. Selling those little cards there can add up and its really the best place to sell cards of that value. If you continue to do shows, buying as a vendor is really important. It’s the best opportunity to buy a % of comps since both parties should know you need room to make money. A slow sales show can be saved by a good buying show. Another tip I have is to really just try things. Come up with a game plan for certain cards and see if it works (obviously don’t go too crazy). Then from there you will get an idea of what you want to do more of and less of. I like to track my transactions to see how they work out in the long run. The more shows you do, the better you will get at it. You just have to take that first step and try it while continuing to learn. Let us know if you have any other questions!
