Spectacular CMQ and CMQ-X Approved Numismatic Treasures Bring Record Prices in the Stack’s Bowers Galleries November Rarities Night Auction
In recent years, the collector has become more sophisticated, explained Greg Roberts, CEO of Stacks Bowers Galleries. Thirty-five years ago, a group of professional numismatists joined forces with David Hall and formed PCGS, and the marketplace was forever transformed. Today, it is not just the highest grades that are desirable, but also coins that are of exquisite eye appeal and quality for the grade. With that in mind, David Hall and I created a new approval service, Collectible Market Qualified. Upon review of each piece and our unanimous approval, CMQ will affix their sticker on a coin. With the combined decades of expertise and credibility in the rare coin market, we anticipated that CMQ would be a welcomed addition to the marketplace.
