DALLAS, TX.- When the Nov. 5-7, 2015 Sports Collectibles Catalog Auction at Heritage closed in the early morning hours of Nov. 8, realizing $11.9+ million in total prices realized, the house became the only sports memorabilia auctioneer to produce an eight-figure event in 2015.

"By the time 2015 is complete," said Chris Ivy, Director of Sports Auctions at Heritage, "Heritage will have more than doubled the 2015 sales of our closest competitor, both in terms of number of consignors and the number of bidders. We are proud to provide unrivaled marketing, exposure, and prices for our clients and it is clear that the hobby has taken notice."

The auction opened on Thursday night, Nov. 5, 2015, with a Trading Card session that accounted for more than $6.6 million overall, upending conventional pricing wisdom across the full spectrum. The evidence was clear in the form of the $227,050 result for a PSA NM 7 example of Mickey Mantle's 1952 Topps rookie as well as in the highest figure ever paid for Ty Cobb E90-1, a staggering $113,525.

Other noteworthy results included $57,360 for a PSA EX 5 example of a 1952 Topps Mantle, just over $43,020 for a 1933 Goudey Lou Gehrig #92 graded PSA NM-MT 8 and $40,630 for a PSA Mint 9 representation of Nolan Ryan's 1968 Topps rookie.

The Friday, Nov. 6, 2015 memorabilia session of the auction was anchored by The Brooks Robinson Collection, which garnered more than $1.44 million, proceeds of which will benefit the beloved Hall of Fame third baseman's charitable endeavors. Three lots topped the six-figure mark, with Robinson's 1964 American League MVP Award taking top billing at $155,350. Robinson's World Championship rings of 1966 and 1970 realized $131,450 and $143,400 respectively.

The Andy Leff Hockey Collection, one of the most significant personal assemblies of hockey memorabilia ever assembled, enjoy its first of several appearances at Heritage in this auction, supplying advanced collectors with a dazzling array of game-used uniforms and gear from the biggest names in hockey, as well as the rings and trophies that punctuated their most glorious moments.
