Who We Are

Magnusson Art Group is a boutique auction house, estate sale company, and appraisal firm based in New Jersey, serving private collectors, families and fiduciaries across the country.

Our team of accredited appraisers and experts provide seamless estate solutions—from cataloguing and valuation to market strategies. Whether working directly with a family or behind the scenes on behalf of a referring partner, we specialize in client care that is both discreet and deeply personal.

Client Care at the
Highest Level

We approach legacy the way the major houses do—by celebrating the story behind the collection.

We craft experiences that celebrate our clients’ taste and legacy. From personalized wall texts and bespoke collection landing pages to dedicated exhibitions and strategic storytelling, every element of our presentation is designed to be persuasive, polished, and deeply personal.

This kind of treatment isn’t reserved for only the most prominent collectors. It’s our standard of care. And it resonates deeply with clients who want their life’s work or personal history treated with reverence.

Why We’re a Natural Partner

Our firm is often called in when the larger auction houses cannot take a full collection—due to scale, scope, or market tier. That’s where we come in, providing:

• Discreet, high-level service with no compromise in presentation

• Appraisal expertise for insurance, estate, and fair market needs

• Multiple sale channels, including auction, estate sale, private sale, and direct purchase

• Marketing and storytelling that reinforce your client’s legacy

• Clear, communicative process that makes you look good for referring us
