Are you interested in consigning property to The Potomack Company? The first step is to send digital photographs of your items to be evaluated by a Potomack appraisal expert. We will contact you with auction estimates for the items, and provide instructions on how to consign.

You may have up to 4 JPG images of each item ready to upload. After submitting the completed form, you will have the option to go back and submit another item.
