Free Online Art Appraisal: A Step-by-Step Guide

An online appraisal allows you to discover the potential auction value of your item without needing to transport it. Here’s how to prepare your submission to get the most accurate and useful estimate.

What an Appraisal Provides

An auction estimate is a probable price range based on the object, its condition, provenance, and current market trends. It is not a guaranteed price; the final hammer price depends on competitive bidding.

How to Prepare Your Photographs

Use natural light and a neutral background.
Take an overall shot, then close-ups of key details: signatures, maker's marks, serial numbers, the underside, and any imperfections.
If necessary, include a photo with a common object to show scale.

Information to Provide

What you know about the item: The artist or brand, medium, and materials.
Its dimensions.
Its history: How you acquired it (e.g., purchase, inheritance) and any supporting documents like invoices or certificates.
Its condition, including any known damage or repairs.

The Appraisal Process

Fill out the consignment form with your photos and information.
One of our specialists will review your submission.
You will receive a free, no-obligation estimate.
If you decide to sell, you'll confirm the consignment and agree on a reserve price, if any.

Example of a Well-Prepared Submission

For a painting, provide several photos (an overall view, the signature, the back with any labels, the frame, a detail of any damage, and a corner of the canvas), its dimensions, medium, the original invoice, and a brief history (e.g., "Purchased from a gallery in 2005"). For a watch, include photos of the dial, the case back with serial numbers, the side profile, the clasp, and its original box and papers.

Helpful Documents

Purchase invoice or gallery receipt.
Certificate of Authenticity or prior expert appraisal.
Gallery or exhibition labels.
Exhibition or auction catalogs where the item is featured.
Correspondence from a previous owner.

Even a seemingly minor document can be a crucial clue to an item's provenance.

Estimate, Reserve, and Hammer Price: Key Differences

Estimate: An indicative price range.
Reserve Price: The confidential minimum price you are willing to sell for.
Hammer Price: The final winning bid at auction.

Factors That Influence an Estimate

Artist or Brand: The reputation and specific period of the creator.
Rarity: Whether it's a unique piece, from a limited edition, or a short production run.
Condition: The item's state of preservation and any restorations.
Provenance: A documented history of ownership.
Market Demand: Current collector interest for that category.

Online Appraisal vs. In-Person Examination

An online appraisal based on photos provides a preliminary estimate. For high-value items or those with uncertain attribution, an in-person examination or further expert opinion may be required before the item can be accepted for auction.
