Certificate of Authenticity: What It Is and Why You Need One

If you're eyeing a new piece for your wall, the first thing you should check is the certificate of authenticity (COA). A COA is a simple paper or digital document that says, "Yes, this artwork is genuine and belongs to the artist or their estate." It’s the art world’s way of saying, "You can trust this piece." Without it, you’re basically buying blind.

Why does a COA matter? First, it protects you from fakes. A fake painting might look great, but if you can’t prove it’s real, its resale value drops to almost zero. Second, a COA helps you track the artwork’s history – its provenance. Knowing who owned it before you adds credibility and can even boost its price.

How to Spot a Real Certificate

Not every COA is legit. Here are the red flags to watch for:

• Signature or seal: Most reputable artists, galleries, or estates sign the document or use an official seal. If the signature looks shaky or the seal is blurry, be cautious.
• Details matter: A solid COA lists the artwork’s title, dimensions, medium, creation date, and the artist’s full name. Vague info like "painting by famous artist" isn’t enough.
• Contact info: Look for a phone number, email, or website you can verify. If the COA only has a generic “Contact us” link, double‑check.
• Paper quality: Professional COAs often use heavy, water‑marked paper. Thin printer paper can be a sign of a quick, fake printout.

If any of these seem off, ask the seller for proof or for a second opinion from an art appraiser.

Getting Your Own Certificate

Artists and sellers can create a COA in a few easy steps:

1. Write the basics: Title, size, medium, date, and a brief description.
2. Add a signature: The artist signs, or a trusted gallery does.
3. Include a seal or hologram: Many artists use a unique stamp or a holographic sticker to make copying harder.
4. Provide a digital copy: Upload a high‑resolution PDF to a secure server and give the buyer a download link.

Some platforms, like Concept Showcase, even let you attach COAs directly to the artwork listing, making verification a breeze for buyers.

When you’re buying online, always ask for a COA before completing the payment. A reputable seller will gladly provide it. If they hesitate, it’s a sign to walk away.

In short, a certificate of authenticity is your safety net in the art market. It confirms the piece’s origin, protects your investment, and makes future resale smoother. Keep these tips in mind, and you’ll feel confident every time you add a new work to your collection.
