Clean Sweep Auctions All-Sport Roadshow Is Coming to Kansas City

Want to know what your quality autograph or collectible is worth?


About Clean Sweep:
Steve Verkman, the President of Clean Sweep Auctions, has been quoted as an expert in authenticity and pricing for vintage sports memorabilia in Newsweek, The New York Times, The Wall Street Journal, CNBC and much more. Clean Sweep has been featured on over 20 television programs throughout the country. Mr. Verkman has done work for the Nassau County District Attorney's office and helped to put a crooked seller in jail and also to organize an auction to benefit the county.

The show is very similar to Antique's Roadshow. We offer free appraisals on all types of sports memorabilia, sports cards, autographs and also vintage celebrity, Presidential and historical autographs.

The difference between us and Antique's Roadshow is that the individual will have the option to sell any item outright or to consign any items to our auction.

The best part about this show is that there is no admission fee of any kind and we will never pressure anyone to sell an item. We provide an honest, free appraisal of all items that people bring with them.
