Selling or appraising cards in Portland?
A card shop isn't only for buying. Many card shops in Portland buy singles, sealed product, graded slabs, and entire collections. If you're thinking of selling, it's worth getting an appraisal first so you know what your cards are really worth — and keep raw cards in sleeves or top loaders, since condition drives the price. Call ahead to confirm the shop is buying right now, and ask whether there's a fee for an appraisal.
