Clear item identity
A guide should name the set, print, language, and variant it covers so the advice is not applied to the wrong item.
Good guidance gives you context, not a shortcut. Use it to ask better questions, then use professional authentication when a decision depends on it.

A guide should name the set, print, language, and variant it covers so the advice is not applied to the wrong item.
Useful images explain what is being compared and where the example came from. A crop without context is not enough.
A guide should say what it cannot confirm. Condition, print variation, and counterfeit methods can make a single check unreliable.
For a purchase where authenticity matters, ask a recognized grading or authentication service for a decision you can rely on.
