Mintventory

Built for collectors who want visibility, accuracy, and a fair Mintventory grading.

Mintventory helps collectors scan cards, grade card quality from front and back photos, track inventory, and browse a searchable card catalog with market-aware insights. Public pages stay indexable, fast, and internally linked; private inventory stays behind login, and grading stays tied to the card record.

Card guide and collector context

Backstory

This canonical record was imported from TCGdex, including official set data, numbering, image references, and available market pricing. It belongs to the HeartGold SoulSilver set. Illustrated by Ken Sugimori.

Pricing rule

Mintventory shows the ungraded / raw market price as the default value for card pages. PSA and other graded prices are separated above so a slab sale never replaces the baseline raw card value.
