Why CardHunt keeps acquisition cost, estimated market value, and your asking price separate in Portfolio.
Cost basis starts with the per-card acquisition price you record. For a multi-copy holding, CardHunt multiplies that unit price by quantity. When another ungraded copy is merged into the same holding, the unit cost becomes a quantity-weighted average.
Market value is an estimate based on pricing data available to CardHunt. A card can temporarily show as pricing unavailable when there are not enough usable comparisons. That is different from a zero-dollar asking price or a missing acquisition cost.
An asking price is the amount you choose to track for a holding marked for sale. It does not change market value, cost basis, or unrealized gain and loss. Keeping it separate prevents a seller’s preference from being mistaken for a market signal.
