Selling a lot vs. selling singles

This article compares selling graded cards as a group lot versus one at a time, so you can pick the route that fits your collection and your time.

You have a stack of slabs and you are ready to sell. The first decision is whether to sell them one by one or move them together. Both can be the right call. Here is how to think about it.

Selling singles yourself

Listing each card on a marketplace can get you the most per card, in theory. In practice you are paying for it in other ways:

  • Fees. Marketplace and payment fees come off every sale.
  • Time. Photos, listings, questions, packing and shipping, for every single card.
  • Risk. Buyers who do not pay, returns, and cards lost or damaged in the mail.
  • Waiting. Slower cards can take weeks or months to sell.

If you have a handful of high-value cards and the time to manage them, selling singles can make sense.

Selling a lot to one buyer

Selling a group of cards to one buyer trades a little top-end price for speed and certainty. One conversation, one shipment, one payment. For collections of 10, 50 or 500 slabs, that difference in time and hassle is huge.

Watch out for lot buyers who cherry-pick. Some buyers take your best cards and leave you holding the rest. Ask up front whether the offer covers everything.

How Cardwel prices a lot

We do not eyeball a pile and throw out a number. Every card in your lot is priced on its own from recent sales, then we add it up. You can see the line items if you want them. If a few cards fall outside what we buy, we tell you which ones and why.

How to send us a lot

  1. List each slab with the grading company and cert number. A spreadsheet or a pasted list works fine.
  2. Add photos if you have them. Fronts are enough to start.
  3. Tell us your asking price if you have one in mind. It helps us move faster.

That is it. Use the paste box on our offer form for lists of any size.
