Its retail salon offers only the highest quality antiques, but it's really as an auction house that DuMouchelles has gained national recognition. Praised as one of the finest in the Midwest, DuMouchelles specializes in fine art, jewelry, sports memorabilia and other, often big-ticket, collectibles. Newcomers shouldn't shy away from the auctions, which host an array of people as fabulous as the items on the block. Recent high-priced items auctioned off include a baseball bat used by the Tigers in the '35 World Series ($5,500) and a Marshall Fredericks bronze statue ($22,500). Kids, don't leave your checkbook at home.
