What questions should I ask a seller to avoid buying a fake?

Ask where the item came from and how long the seller has had it. Ask whether it has been repaired, restored, or altered, and whether the seller guarantees its age or authenticity. A reputable seller will answer clearly and will not be offended by questions.

For higher-priced items, request a written description that includes what the seller believes the item is, its approximate age, and any known repairs. Ask about the return policy if the item is later found to be misdescribed.

Be cautious of a seller who refuses to answer, pressures you to decide quickly, or offers a price that seems too good to be true for an important piece. When in doubt, take photos and ask a specialist dealer, collector, or appraiser for an opinion before buying.
