Restored, Reworked or Reproduction: The Verdicts That Aren't Simply 'Fake'

Collectors brace for a binary — real or fake. In practice most negative or partial results fall between, and the distinctions matter, because they determine value, disclosure obligations and whether you can sell the piece at all.

Reproduction

Made recently, in its entirety, in imitation of an ancient form. Not inherently dishonest — reproductions are made for teaching, for demonstration and by knappers practising a craft, and many are signed by their makers. It becomes fraud only when represented as ancient.

Value: generally modest, though work by a well-known modern knapper has its own small market. Disclosure: mandatory in any sale.

Restoration

A genuinely ancient piece with missing material replaced — a rebuilt tip, a filled break, a reconstructed vessel. Legitimate, common and often skilled. The question is never whether restoration happened but how much, and was it disclosed.

The distinction that matters commercially is between stabilisation, which prevents further damage, and cosmetic restoration, which changes the apparent completeness of the piece. The second affects price substantially.

Value: reduced relative to an intact example, in proportion to the extent. Disclosure: mandatory, with the extent stated. "Restored" without a percentage is not adequate disclosure.

Reworking

The genuinely difficult category. Ancient material re-flaked in modern times into a more valuable form — a broken or unremarkable piece worked into a recognised type. The stone is old. Patina on untouched surfaces is old. Parts of the object are entirely authentic.

It is also the category most likely to fool an experienced collector, because everything that a quick check tests comes back correct. What gives it away is fresh flake scars cutting through old patina, visible under magnification and raking light — which is exactly why authenticators care about patina inside flake scars rather than surface colour.

Value: substantially below a genuine example of the type; it is not an example of that type. Disclosure: mandatory.

Ancient reworking, which is a different thing entirely

Confusingly, prehistoric people also reworked their own tools — resharpening, repurposing a broken point, reducing a form as it wore down. This is entirely authentic and part of the object's history rather than a defect. A good authenticator distinguishes ancient rework from modern by the patina on the reworked surfaces, and will explain which they are describing.

"Consistent with" and "cannot determine"

Two further outcomes worth expecting. "Consistent with" is a genuine, honest and useful verdict: nothing observed contradicts the attribution, but the evidence does not establish it conclusively. "Cannot determine" is equally honest, and is a better answer than a confident guess. Neither is a failure of the authenticator.

What to do with a partial result

• Keep the full written opinion with the piece, permanently. Suppressing it converts an honest object into a dishonest sale later.
• Disclose it in full when you sell, in the listing rather than on request.
• Reprice realistically — a restored or reworked piece has a market, just a different one.
• If you bought it as genuine, act quickly: check the return terms and raise it with the seller while the transaction is recent.

Find an authenticator who will give you the detail behind the verdict, not just the verdict.
