How to Authenticate Original Art — Certificates, Provenance, and What Matters

Verifying that a painting is genuine is not as intimidating as it sounds. Here is what documentation actually matters, and what you can safely ignore.

How to Authenticate Original Art — Certificates, Provenance, and What Matters

The Authentication Myth

Many new collectors assume that authenticating art requires a forensic laboratory, an art historian, and a five-figure bill. The reality for contemporary art purchased directly from working artists is far simpler. You do not need a Rembrandt-level investigation to verify a painting made by a living artist — you need the right documentation and a basic understanding of what matters.

The Certificate of Authenticity: What It Is and What It Is Not

A Certificate of Authenticity (COA) is a document signed by the artist or an authorized representative that confirms a specific work is a genuine original. It typically includes the title, dimensions, medium, date of completion, the artist's signature, and sometimes an edition number for print works.

What a COA does: It establishes a direct link between the artist and the work, creating a paper trail that follows the painting through its life.

What a COA does not do: It is not a legal document issued by a regulatory body — there is no government agency certifying art. The value of a COA lies entirely in the credibility of the person who signed it.

This is why buying directly from the artist is the gold standard of authentication. When the person who physically created the painting signs the COA and can confirm its authenticity through photographs, process documentation, and direct communication, the chain of trust is as short and strong as it can possibly be. Every painting in the Lei-Kol collection ships with a signed COA from the artist herself.

Provenance: The Paper Trail

Provenance is the documented history of an artwork's ownership. For contemporary art, provenance documentation includes the original purchase receipt, any subsequent sale records, exhibition history, and correspondence with the artist or gallery.

Even for a recently completed painting, good provenance starts the moment the work is first sold. Keep your original receipt, your COA, any photographs of the work in progress provided by the artist, and correspondence about the purchase. Ten years from now, that folder of documents will be every bit as valuable as the painting itself when it comes to resale or insurance.

Red Flags When Buying Art

  • No COA available: If the seller cannot provide any documentation connecting the work to the named artist, walk away — regardless of how convincing the story sounds.
  • Hesitation about the artist's identity: Legitimate artists are happy to verify their work. If a seller is reluctant to put you in contact with the artist, there is a reason.
  • Prices that seem too good: If a piece is priced at a fraction of comparable works by the same artist and the seller cannot explain why, be suspicious.
  • Vague or conflicting provenance: If the ownership history is fuzzy or changes from telling to telling, the piece may be stolen, forged, or misattributed.

Why Buying Directly Eliminates Authentication Risk

The simplest way to guarantee authenticity is to buy from the artist. When you purchase a Lei-Kol original from Physical Art for Crypto, the artist herself handles the transaction, signs the COA, and is available to confirm the work's authenticity at any point in the future. There are no intermediaries, no questionable provenance gaps, and no ambiguity about who made the work.

This is one of the often-overlooked advantages of the direct-to-collector model. Gallery authentication relies on the gallery's reputation; artist-direct authentication relies on the only person whose word actually matters. Browse the collection and buy with total confidence — every piece comes with full documentation directly from the creator.
