Editorial Guidelines

Last updated: May 2026

This page is the working contract between our editorial team and our readers. It explains how we choose what to cover, how we research and fact-check, how we use sources, what we do when we make a mistake, and how to flag content that doesn’t meet our standards. We update it as our process evolves.

What Collectibles Multiverse covers

We cover physical collectibles — items that exist in the world, that change hands at auction or between collectors, and that have a documented history of value. The categories we currently publish across include comics, coins, sports cards, trading card games, watches, vintage toys, video games, vinyl records, books, banknotes, stamps, sneakers, retro tech, and a growing list of pop-culture memorabilia. We deliberately do not cover speculative digital-only categories, gambling adjacent products, or items whose primary use is anything other than collecting.

How we choose topics

An item, list, or guide gets commissioned only if it answers a question a real collector might type into a search engine. We start every article with a working question — “How do I tell a Shadowless Charizard from an Unlimited?”, “Why do some 1909-S VDB pennies sell for more than others?” — and we keep editing until the article answers that question better than the search results currently do.

Research standards

Our research workflow follows three rules:

Sourcing pricing data

Pricing references in our articles come from one of: Heritage Auctions, Goldin, Christie’s, Sotheby’s, Phillips, RR Auction, eBay sold-listings (with caveats), PCGS price guides, PSA Auction Prices Realized, GoCollect, GoldinDB, and direct manufacturer ARP figures. We avoid asking-price aggregators because they reflect what a seller hopes to receive, not what a buyer has paid.

Authentication and grading references

When we describe an authentication or grading framework, we describe the company’s published methodology — not unofficial collector folklore. PSA, BGS, CGC, SGC, JSA, PSA/DNA, PCGS, NGC, WATA, AFA, VGA, and TPG all publish guidelines; we cite those documents and note where actual practice has diverged from the published method.

Use of AI

Editorial AI tools are used for first-draft outlines, copyediting passes, and image-search assistance. Every article that publishes on Collectibles Multiverse has been read, fact-checked, and approved by a human editor before going live. Any AI-generated illustration would be labelled as such in the caption; we do not currently publish AI-generated illustrations as authoritative reference photos.

Independence from advertisers

Our affiliate partners and display-advertising networks have no influence on editorial decisions. No advertiser sees an article before publication. We do not accept sponsored content, paid placement in lists, or money in exchange for review verdicts. If we ever publish a sponsored piece in the future, it will be labelled “Sponsored” at the top, the body, and the URL — and it will be clearly visually distinct from editorial content.

Corrections policy

When a published article contains a factual error we add a correction box at the bottom of the article describing what was changed, when, and why. We do not silently edit historical content to make ourselves look more accurate than we were. Major corrections (a wrong price, a wrong attribution, a wrong year) are flagged in the article and noted in our public corrections log.

Conflicts of interest

If an editor or contributor personally owns or actively trades in the category they are writing about, that relationship is disclosed at the top of the article. Editors are not permitted to trade in items they have written about for 30 days after publication.

Reader feedback

If you spot an error, disagree with a verdict, or have a source we missed, please email the editorial team. Specific page URLs and direct quotes get a faster response than general criticism. We read everything; we cannot promise to reply to everything.
