How to track inventory, quantities, variants and estimated value in Cardmine.
My cards is your personal inventory. It is where you save cards you own, track quantities, organize collections and follow estimated value over time.
You can use it as a lightweight collection tracker or as the starting point for marketplace listings.
From a card or set page, choose the card you want to save and add it to your collection. Pick the variant and quantity carefully. If the card has multiple versions, saving the right version matters for both inventory accuracy and value estimates.
Collections let you group cards in a way that matches how you collect. You can keep one main collection, split by game, separate trade binders from personal cards, or create smaller lists for a set chase.
Collection totals update from the latest known prices. If a card has no current price, it may still appear in your collection but not contribute to the value total.
Inventory-backed listings are easier to manage because the listing starts from a card you already saved. You can choose condition, price, quantity and photos from the seller flow.
If you plan to sell, keep your inventory clean:
Collection value is an estimate based on available market data. It helps you see direction, but it is not a guaranteed sale price. The final marketplace result depends on buyer demand, condition, listing quality and shipping cost.
