Leonard Auction, located in Addison, Ill., is a premiere Chicago auction house and estate liquidation firm that has won multiple awards on Proxiblog in such categories as photography, lot descriptions, consignments and overall best house. Leonard Auction also has detailed consignment policies that secure some of the best coin lots on the Proxibid portal. The company not only knows numismatics but also ranks as one of the best coin-grading houses, too, as we reported in this 2012 post. The company also protects buyers; its policy on coin authenticity is among the most progressive on Internet, as we emphasized in this 2011 post.

Leonard Auction has a reputation for experience, integrity, and superior technology–core values of founder and appraiser John Leonard–that propelled his house to the top echelon of auctioneering. The company’s first auction house in Naperville, Ill., opened in 2006. Business boomed, prompting the company a year later to relocate to its current site in Addison, Ill., featuring more than 8,000 square feet for ample display.

Leonard Auction’s onsite prowess combines with digital savvy to bring the excitement of an auction to coin buyers on Proxibid. The company conducts a series of auctions each month. Its Coin & Currency auctions feature 300-400 lots of high-end collectible coins, currency, gold, silver, platinum and stamps.

We have marveled at how Leonard Auction continues to improve as the technology does, providing ever sharper photos and lot descriptions and attracting competitive bidding in the spirit of auctioneering.
