Historic flannels and bats connected to some of the biggest names in baseball history have surfaced in one sports memorabilia company’s final auction of 2009.

Browsing the current MEARS auction is a little like walking into an All-Star lockerroom from some bygone era.

The Milwaukee-based memorabilia evaluation and research company is celebrating the first anniversary of its auction division with a special event featuring about 200 high quality pieces of sports memorabilia, heavy on items once used by Hall of Famers. The auction launched Tuesday.

The highlights include a 1966 Roberto Clemente home uniform (minimum bid $69,000). Grading out an A9, the ensemble represents the only known home offering in the hobby from Clemente’s only MVP season. Also offered is a 1954 Warren Spahn Milwaukee Braves road jersey (A10). The jersey was offered with provenance provided by former Braves’ batboy Ed Quinn, whose mother acquired it while employed by the team as a switchboard operator. Minimum bid on the Spahn jersey is $36,000.

Other jerseys include an autographed 1970 Pete Rose road jersey (A10), a 1956 Stan Musial road jersey (A10) and a 1966 Eddie Mathews road jersey (A 10).

Bat collectors will have the opportunity to acquire rare Hall of Fame lumber from Jackie Robinson, Mickey Mantle, Ty Cobb, Walter Johnson, Grover Cleveland Alexander, and Rogers Hornsby among others. The Robinson bat quickly reached the minimum $35,000 bid within hours after the auction opened Tuesday.

The bat selection also includes a grouping all the starting position players from the 1976 World Champion Cincinnati Reds (MB $15,000). Each bat bears the 1976 American bicentennial stamping applied by Louisville Slugger. The collection includes bats used by Pete Rose, Johnny Bench, Joe Morgan and Tony Perez.

Rounding out the collectibles field are items running the gamut from rare single signed autographed items to vintage pennants and photographs, a program and ticket stub from Roger Maris’ 61st home run game and even leather football helmets.

MEARS auctions have attracted a strong following thanks in part to an industry low 10% buyer’s premium. The company also promises no hidden reserves, no in-house bidding, and promises to cover purchases with its own Buyers Protection program.

The special auction will run through December 10th. Registration and information can be found on the company’s website.
