We have been serving buyers and sellers for nearly 100 years and therefore have tremendous brand recognition and our Detroit gallery is in a highly visible and trafficked area - directly across from the landmark Renaissance Center. We conduct auctions monthly so the time from consignment to getting you paid is substantially shorter than other auction houses – and can be as quick as two months. Our team of experienced experts, photographers, and support staff provides outstanding client service and transactional ease. We attend to the details of bringing your items to market, and our comprehensive marketing strategy ensures that your collection is extensively marketed to maximize exposure and prices realized, while professionally representing your collection to the most qualified collectors around the globe. Our marketing program is included in our fee:

• We provide collectors with detailed and researched descriptions, condition reports and high definition photography

• In-Home Visit —If you have multiple items or a large collection, please call us at 313-963-6255 to discuss your items and determine if we can schedule a complimentary appointment with an appraiser to visit your location. Our appraiser will do a walk through and provide verbal estimates on relevant items and discuss which items can be auctioned. We serve Michigan and out-of-state collections.

Once our appraisers have accepted your items for consignment, we will provide you a Consignment Agreement with the terms of sale. Our commission is calculated on a sliding scale dependent on the final hammer price - the more that an item sells for, the less commission is drawn..

Once the Consignment Agreement has been completed, we will schedule a mutually agreeable delivery date to our Detroit gallery. Should you require assistance, our gallery can assist you with potential shippers and they can provide you with complimentary quotes.

Your items will be catalogued, photographed, and placed in our next available upcoming auctions. Our online, transparent bidding process allows you to follow the sale from the posting of the auction catalogue through the final sale.

Within a week after the auction, you will receive a preliminary settlement statement. and your proceeds will be mailed to you within 4-6 weeks after the purchasers have paid for and received your items.
