Cardboard Grail publishes collector guides to explain how cards are identified, assessed, stored, packed and sold. Store inventory and commercial relationships can influence which subjects we cover, but they do not change the standards below.
Guides distinguish authentication from condition. We compare card details with known genuine examples and record visible wear using the condition terms shown on the storefront. A guide is not a substitute for an in-person inspection or third-party grading.
Original photographs are identified as Cardboard Grail images. Product photographs aim to show the actual card or product where practical. Lighting, sleeves and display settings can affect how surface marks and colours appear.
Release dates, tournament rules and grading requirements should link to the publisher, organiser or grading company. Market claims must state their source and date. We do not present collectables as guaranteed investments.
We update guides when product details, release schedules or rules change. Material corrections should be made promptly and the page should show its latest review date when the publishing system provides one.
Cardboard Grail sells some of the products discussed in its guides. Links to our collections are commercial links. Any paid placement, supplied product or affiliate relationship must be disclosed on the relevant page.
