From the slab to the book.

One card, from the moment it comes in to the line in your ledger.

  1. The graded slab inside the scanner’s corner marks.

    Scan or add

    Scan the cert on a graded slab with your phone, or add a raw card from the catalog.

  2. The same slab, marked as matched to its card.

    Confirm the card

    Check the match, printing and grade. Add your pictures, your cost and where the card is kept.

  3. The same slab, marked as valued from recorded sales.

    See its value

    Values draw on recorded sales. Estimates and cards still waiting for a value are marked.

  4. The same slab, marked as entered in the ledger.

    Keep it in step

    List the card, then record the buy, sale or trade against it in your ledger.

Know what you hold.

Every card keeps its pictures, printing, grade, cert number and where it is kept. Search and filter the whole book to find one.

A value needs a source.

Your purchase cost is the record of your deal. A market value is a reference for your next one.MDC matches a card by identity and grade to recorded sales and shows where each figure came from. Coverage varies by card, and a card still waiting for a value is marked as waiting.
