About SCP Auctions

SCP Auctions is one of the nation’s largest auctioneers and private sellers of important sports memorabilia and cards, and is considered a leader in its industry. Founded in 1979 by David Kohler, SCP Auction’s record speaks for itself, as the company has realized record auction and private sale prices for items including the c. 1920 Babe Ruth New York Yankees game worn road jersey ($4.415 million); the 1857 “Laws of Base Ball” document set ($3.263 million); T-206 Honus Wagner card ($2.8 million); Jesse Owens’ 1936 Olympic gold medal ($1.466 million); the bat Babe Ruth used to hit the first home run in old Yankee Stadium ($1.265 million); the contract that sent Babe Ruth to the Yankees from the Red Sox ($996,000); Barry Bonds’ record-breaking No. 756 home run ball ($752,467); and Babe Ruth’s gold pocket watch presented to him by the New York Yankees during his last appearance at Yankee Stadium in 1948 ($650,108). The company’s consistency and industry knowledge have helped to maintain SCP Auctions’ stellar reputation as a dominant figure in the sports memorabilia world, and it is highly visible throughout the category due to its presence at major collectibles shows across the country and placement in all the major trade publications.

SCP Auctions principals David Kohler and Brendan Wells have more than 70 years of combined industry experience and dealing in vintage sports cards and memorabilia isn’t just their jobs – it’s their passion. SCP Auctions has the expertise for every collector’s interest, whether your passion is in 19th century material, high grade PSA/SGC cards, game-used pieces or single cards and sets.

SCP Auctions, the only sports memorabilia company to have partnered with storied auction house Sotheby’s, is constantly striving to uncover incredible collections and offer the most interesting, valuable and unique collectibles possible. The private collections of Honus Wagner, Casey Stengel, Pee Wee Reese, Wilt Chamberlain, Bob Cousy, George Mikan, John Havlicek, Dr. J, Paul Hornung, Ozzie Smith, and Oscar Robertson are just some of the one-of-a kind offerings that the company has presented collectors.

SCP Auctions is happy to offer suggestions and guidance on how to get the most out of any collector’s budget. SCP Auctions prides itself on customer service and speedy responses to any issue or inquiry, and calls many of the nation’s top collectors its clients and, more important, friends. SCP Auctions has aided collectors in their own collection sales, including both the Bill Nowlin and Bill Riddell historic bat collections, featuring game-used bats from Ty Cobb, Babe Ruth, Roberto Clemente, Ted Williams and Lou Gehrig; the Mitsuhiko Fujita collection spanning the 1928, ’31, and ’34 major league all-star tours to Japan; the Kirk Harris T206 tobacco card collection; and the esteemed collection of Dr. Douglas Triplett’s “regionals” and test-issue single cards. We know we wouldn’t be able to succeed without your active participation, and we value our relationships with collectors and consignors alike.

Brendan Wells

Auction Director

Brendan came to SCP Auctions in July 2013 after working for Upper Deck just a short drive down the I-5. He was an avid card collector in his youth until playing sports took over. While he may be more proud of his team sports adolescent glory days in soccer, basketball and baseball, it was middle-distance running that gave him the opportunity to compete on the cross-country and track teams at Duke University (and, admittedly, to get into the school). He dabbled in the financial services industry before earning an MBA in Sports Business and turning his attention back to sports marketing and memorabilia.

Having grown up in the Bay Area, Brendan remains a loyal Giants, 49ers and Warriors fan, and is proud of his NorCal roots in spite of how soft SoCal has made him. He is most passionate about baseball having heard countless stories from his father, who pitched for the Dodgers organization in the 50’s and 60’s. A numbers guy and people person, Brendan feels lucky to be able to go to work each day living and breathing sports.

Rich Atherton

Inventory Manager

Rich began collecting baseball cards in 1979. When all the other kids would get candy and ice cream from the ice cream truck, he would buy packs of baseball cards. Rich’s hobby career began in 1989 working at a local card shop and continued through 1997, before coming to SCP in 2008. Always a collector, he is currently working on a ‘59 Ted Williams Fleer set graded PSA 8 or higher. Rich cheers for the L.A. Dodgers and Anaheim Ducks when time allows.

She enjoys working at SCP Auctions and learning about different sports and being surrounded by people with so much passion for sports and important sports memorabilia.
