Start on the exact checklist, including edition and parallel
Find the correct year, brand and set before adding a large group. Verify several card numbers and names against the cards in your hands. Inserts, parallels and regional editions can share a player and similar design while belonging to different lists. A wrong checklist selection creates plausible-looking matches for cards you do not actually need.
Choose one manageable project for your first pass rather than importing every card you own. A ten-card demonstration set is enough to understand the logic. In a real set, confirm the numbering convention and any variations before using bulk selection. Review the first, middle and last selected entries afterward; one mistaken range can produce dozens of false wants or trade offers.
Separate possession, demand and available duplicates
TCDB defines a collection as items you possess, a want list as items you would like to acquire and a for-sale/trade list as owned items you would like to move. Those definitions are the foundation of useful matching. Do not add a hoped-for purchase to owned inventory or put your only keeper copy on a trade list unless you intend to exchange it.
In our fictional ten-card set, you own numbers 1–6 and want 7–10. You also have one extra copy each of 2 and 5. That means six distinct checklist positions are complete, eight physical cards are held and two cards can be offered without breaking the set. Distinct-card count and physical quantity answer different questions.
| List or count | Entries | Meaning |
|---|---|---|
| Collection positions | 1, 2, 3, 4, 5, 6 | Six different cards owned |
| Want list | 7, 8, 9, 10 | Four positions still missing |
| Available duplicates | One extra #2 and one extra #5 | Two copies offered for exchange |
| Physical total | 8 cards | Six keepers plus two duplicates |
Check a small sample before relying on matching
After entering the lists, reopen a few card records and compare them with the physical copies. Check that the wanted version is correct and that the duplicates really exist in the stated condition. Separate a damaged duplicate from a cleaner keeper in your own notes. A database quantity does not describe condition unless you have recorded that distinction.
Mark cards already committed to another trade in a way you can reliably track and keep availability current. If you cannot physically locate a listed duplicate, remove it from consideration until you find it. This small reconciliation step is more efficient than apologizing after a partner accepts an offer. It also makes the eventual packing list clear: the outgoing copy is the spare, not whichever card you happen to pull first.
Run the report and read it as a starting point
The official TCDB manual shows the route from your username to Collections, then Tools, Trade tools, Trade Matching and Run Report. Use the current account controls for any report availability or repeat-run limit; this guide does not assume a universal limit for every account. Wait for the report result rather than repeatedly changing your lists while trying to interpret it.
For the fictional set, another collector might offer #7 and want your duplicate #2. That is a possible exchange, not an agreed transaction. Review their list, activity and trading preferences, then confirm the actual copy and condition. A report that shows many matches can still be less useful than one small exchange that both collectors can fulfill accurately.
- WantYou need #7 from the example set.
- OfferYour spare #2 is available.
- MatchAnother list contains the opposite need.
- ReviewConfirm copies, condition and mailing terms.

Record the agreement and update the lists after completion
Before accepting, agree on each card, quantity, condition and shipping arrangement. Keep the discussion attached to the transaction where possible and use the same item list when packing. A match count is not a valuation formula; one collector may prefer several common cards while another wants a particular single. Clarify what both sides actually accept.
When the incoming cards arrive, inspect them against the agreement before marking the project complete. Update the want list and physical inventory, reconcile outgoing duplicates and leave factual feedback through the platform. In our example, receiving #7 moves the set from six to seven completed positions, while trading one spare #2 still leaves your keeper in place. That small numerical check catches accidental double counting and makes the next match more useful.
Frequently asked questions
What is the difference between the three TCDB lists?
Collection records what you have, the want list records what you seek and the for-sale/trade list records owned cards you are willing to move. Keep those purposes distinct.
How do I avoid adding the wrong parallel?
Verify the exact set and version before bulk entry, then compare a sample of card numbers and images against your physical cards. Similar names can belong to separate checklists.
Where do I find Trade Matching?
The official manual shows Collections, Tools, the Trade tools section and Trade Matching, followed by Run Report. Use your account’s current controls for availability and repeat-run rules.
Why might a match not become a trade?
Lists can be outdated, copies can differ in condition and collectors can have different shipping or collecting preferences. A match starts a review; it does not commit either person to an exchange.
