Authentication, Appraisal and Grading: Which One Do You Actually Need?

These three words get used interchangeably and they mean quite different things. Buying the wrong one is the most common and most expensive procedural mistake in collecting.

Authentication answers: is it what it is said to be?

An authentication is an opinion on genuineness and identity. Is this object actually ancient, is it the type it is being called, has it been restored or reworked, is it a modern reproduction. It says nothing about value.

Appraisal answers: what is it worth?

An appraisal assigns a value for a stated purpose — insurance, estate, donation, sale — using comparable sales and market knowledge. Critically, an appraisal generally assumes the attribution already holds. It prices the thing you tell it you have.

That is why the order matters. An appraisal of a piece that turns out not to be genuine is not a small error, it is a worthless document. Authentication first, then appraisal.

Grading answers: what condition is it in, on a standard scale?

Grading is most developed in coins and currency, where established scales and third-party services dominate the market. It measures condition and quality against a defined standard. In artifact collecting, grading in this formal sense is much less established, and language borrowed from coin grading should be read carefully rather than assumed to mean the same thing.

Where the confusion costs money

• Insuring on an appraisal alone. If a claim is ever made, the insurer may examine the piece. An appraisal built on an unexamined attribution can collapse at exactly the moment you need it.
• Buying on a "certificate" that is really neither. Some documents in circulation state a value with no examination behind it. That is a price tag, not a certificate.
• Paying for an appraisal to answer an authentication question. Common when someone inherits a collection and wants to know "what it is worth", where the real question is what they actually have.

Which one do you need?

• Considering a purchase — authentication.
• Told a piece is a specific rare type — authentication.
• Insuring a collection — authentication on the significant pieces, then appraisal.
• Settling an estate or dividing a collection — both, in that order.
• Selling — authentication reliably widens the buyer pool; appraisal helps you set expectations.
• Coins and currency — grading and authentication frequently come together through the same service. Ask which you are buying.

Can one person do all three?

Sometimes, and there is nothing wrong with that when disclosed. But be alert to the conflict when the same person authenticates, appraises and offers to buy. Each step narrows the range of the next, and one party controlling all three is not a position you want to be on the other side of.
