Mack C. Chase Walking Liberty Half Dollars Bring Nearly $2.5 Million

Costa Mesa, CA Stack’s Bowers Galleries, a legendary rare coin auction firm, is proud to announce that records were shattered in their September 3, 2026, offering of the Mack C. Chase Collection. Held in conjunction with the firm’s Summer Global Showcase Auction (an Event Auctioneer Partner of the ANA’s World’s Fair of Money), the exceptional offering of 253 lots realized $2,448,125 after a fiercely contested session. Achieving the highest price in the Mack C. Chase Collection was lot 4050, one of the finest examples of the key 1921-D. Graded MS-66 by PCGS and approved by CAC and CMQ, this coin realized a record $183,000. Also smashing prior auction records was the sole finest 1917-D with reverse mintmark, graded PCGS MS-67, that brought $122,000. (All prices include the buyer’s premium.)

“We knew from the beginning that the Mack C. Chase Collection was something special, and it was great to see collectors respond so enthusiastically,” commented John M. Pack, executive director of consignments for Stack’s Bowers Galleries. “Mack built this collection over many years with tremendous patience and a keen eye for quality. It was rewarding to see that recognized with such strong results and record prices.”
