How to Store and Preserve Your Certificate of Authenticity

You've invested in an original painting — and it came with a Certificate of Authenticity (COA). That document is more than a formality. It's the legal and historical record of your artwork's origin, and losing it can affect the piece's provenance, insurability, and resale value.

Here's how to keep it safe for years — and generations — to come.

Why Preserving Your COA Matters

A Certificate of Authenticity is a physical document, and like all paper, it's vulnerable to moisture, light, heat, and time. A faded, torn, or missing COA can raise doubts about an artwork's legitimacy — even if the painting itself is in perfect condition. Collectors, insurers, and auction houses all rely on documentation, so protecting yours is as important as protecting the artwork.

1. Never Fold It

Folding creates permanent creases that weaken the paper fibres over time. Always store your COA flat or rolled — never folded. If it arrived folded, gently flatten it under a heavy book for a few days before storing.

2. Use Archival-Quality Storage

Standard plastic sleeves and folders contain acids that degrade paper over time. Instead, use:

  • Acid-free plastic sleeves — available at art supply or archival stores
  • Acid-free folders or envelopes — for flat storage
  • Archival boxes — for long-term storage of multiple documents

Look for products labelled "archival quality", "acid-free", or "lignin-free".

3. Store Away from Light, Heat, and Moisture

The enemies of paper are UV light, humidity, and heat. Store your COA:

  • Away from direct sunlight or fluorescent lighting
  • In a cool, dry environment — ideally between 15–21°C (60–70°F)
  • Away from basements, attics, or bathrooms where humidity fluctuates

A climate-controlled room or a fireproof document safe are ideal options.

4. Make a Digital Copy

Scan your COA at high resolution (at least 300 DPI) and save the file in multiple places — a cloud storage service, an external hard drive, and your email. A digital copy won't replace the original for legal purposes, but it provides a backup record of the document's contents if the original is ever lost or damaged.

5. Keep It with the Artwork's Records

Create a simple folder — physical or digital — for each artwork you own. Include:

  • The Certificate of Authenticity
  • The purchase receipt or invoice
  • Any correspondence with the artist or gallery
  • Photographs of the artwork (front and back)
  • Insurance documents, if applicable

This "provenance file" becomes invaluable if you ever sell, insure, donate, or pass on the piece.

6. Consider Professional Framing for Display

If you'd like to display your COA alongside the artwork, have it professionally framed using UV-protective glass and acid-free matting. This protects it from light damage while keeping it visible and accessible.
