We provide expert Authentication and Insurance Appraisals for valuable collections. Our licensed team delivers professional reports that accurately reflect market value and support insurance claims in the event of theft, fire, or damage.

For clients ready to sell, we offer Pre-Auction Advisory. We list select collections in our private Pre-Auction database, giving qualified collectors and high-net-worth buyers the opportunity to review and submit offers before the items are released to the general public on platforms like eBay, Goldin Auctions, or Christie’s.

This controlled, discreet process protects sellers by reducing competition and often results in stronger prices, while giving serious buyers privileged access to exceptional material.

At its core, Excellent Standard acts as a trusted intermediary — authenticating assets, protecting value through proper appraisal and insurance documentation, and quietly connecting collections with the right buyers.

We do not operate as a traditional retailer. We focus on high-touch consulting, asset protection, and strategic deal facilitation for those who treat collectibles as serious investments.
