Concierge for graded sports cards on Courtyard, Arena Club, and eBay — hold, list, or skip, with the number after fees.
You still click buy and sell. We tell you which print matters and what the tape says after fees.
Every slab marked sell, watch, hold, or skip — right card vs the wrong print of a famous name.
List, bid, or walk — net after Arena Club, Courtyard, and eBay fees. Seasonal windows included.
Paste a Courtyard link, Arena ask, eBay listing, or package. One verdict. You execute.
Tell us about your book — sports, platforms, roughly how many slabs. We’ll reply from hello@slabwire.cards.
