HoloGem values the cards you actually own rather than applying one generic price to every version of a card.

Your collection value can take into account the exact card, variant, condition, quantity and grading information attached to each copy. A graded copy can therefore use the relevant graded market value instead of being treated like an ungraded card.

To correct the details of a card you own, open the card from your Vault and tap your Vault entry. Your collection value will then reflect the information saved for that copy.

You can see your estimated total collection value and market movement from your collection and Home views.
