Goodson Gallery’s Expert Appraisal Process: Where Passion Meets Precision in Art & Antiques

At Goodson Gallery, every appraisal is a gateway into history. Founded by Michael Vallone, our gallery blends over a decade of hands-on experience in the art and antique world with cutting-edge research tools and a global network of niche experts. Whether you’re evaluating a 19th-century portrait, a sculptural artifact, or a rare ephemera piece, we offer precise, research-backed valuations rooted in authenticity, data, and a love for the craft.

How We Determine Value: A Multi-Layered, Expert-Led Approach

Our appraisal process begins with a rigorous verification of provenance—establishing where the item came from, who owned it, and how it fits into historical context. We analyze maker’s marks, ownership records, exhibition mentions, and physical clues like inscriptions or gallery labels.

Next is a meticulous physical examination. Our experts assess condition, craftsmanship, materials, and any restorations, documenting all findings with high-resolution images and notes. Scientific tools may be used when deeper analysis is required.

Then we conduct a comparative market analysis (CMA), sourcing data from major auction house archives, historical sales databases, and online platforms. This lets us compare your piece to similar items, adjusting for variables like rarity, demand, and period authenticity.

Tools That Power Accuracy: Experts, Databases, and AI

Goodson Gallery is known for merging traditional expertise with modern research capabilities. Our team uses:

• Auction and sales databases to reference past sale prices and trends.
• Advanced AI tools to comb online archives, forums, and institutional collections.
• A network of vetted specialists who cover everything from vintage guitars to ancient artifacts.

This combination helps us spot subtle details, verify claims, and discover hidden value others might miss.

Clear Service Tiers for Every Collector and Seller

We offer appraisal services in structured tiers, so you always know what you’re getting—and what it costs.

All appraisals come with a professional PDF report that provides transparent conclusions and contextual research to support your next move—whether you’re planning to sell, archive, or acquire.

Provenance: The Hidden Force Behind Value

Provenance can significantly increase an item’s value by proving authenticity, establishing historical context, and generating trust among buyers and institutions.

We examine:

• Sales history, private collections, and previous exhibitions
• Physical clues (stickers, engravings, old gallery tags)
• Verified references in archives, databases, and publications

When provenance is unclear, we dig deeper using AI-powered searches and direct outreach to experts and institutions.

More Than a Number: Strategic Support for Buyers and Sellers

At Goodson Gallery, we know valuation is just the first step. That’s why we help clients use the information strategically—whether you’re preparing for a sale, building a collection, or debating whether to hold or part with a piece.

Our post-appraisal services include:

• Selling strategy guidance (auction vs. private sale)
• Venue and timing recommendations to maximize returns
• Presentation consulting to improve appeal and visibility
• Collector insight to help evaluate long-term potential
• Referral to restoration or authentication professionals when needed

And everything is done with discretion, accuracy, and a focus on your long-term goals.
