In short
Tracking your collection's value turns a shoebox of cards into a portfolio you can actually manage, and you can do it for free. The steps are simple, and the payoff is knowing what you own, what it is worth, and whether you are up or down.
List what you own
Add each card and sealed item to a collection, including quantity.
Choose a price source
Use Cardmarket for Europe, TCGPlayer for the US, and eBay and Fanatics solds for graded slabs.
Record condition and grade
Note raw condition or grading company and grade for each item.
Add your purchase price
Enter what you paid so the tracker can calculate profit and loss.
Track value and set alerts
Follow portfolio value over time and get notified on significant price moves.
Your value is only as good as its source. European collectors should use Cardmarket (euros); US collectors TCGPlayer (dollars); graded slabs are best valued from eBay and Fanatics sold listings. See our guide on Cardmarket vs TCGPlayer vs eBay, and our ranking of the best free trackers, to choose a tool that uses the right sources.
Condition and grade change value a lot, so record them per item (for example PSA 10 vs raw near mint). Then add what you paid. Without a cost basis you only see current value; with it you see real profit and loss.
Check in periodically and use alerts for big moves. A dedicated free tracker updates prices for you and charts your portfolio over time so you do not have to recalculate by hand.
Add your cards to a tracker that values them with market prices. For Europe use Cardmarket (euros), for the US TCGPlayer, and for graded cards eBay and Fanatics sold prices. CollectHolo combines all of these for free and totals your portfolio automatically.
Yes. CollectHolo's core tracking, including portfolio value and profit & loss, is free. Optional PRO tools (Market Pulse, Ending Soon, Recent Sales) add deeper market insight but are not needed for the basics.
Only if you want profit and loss. Entering your cost basis lets the tracker show whether each item, and your whole collection, is up or down versus what you paid.
