On July 11, 1914 the greatest player in baseball history, Babe Ruth, played his first MLB game and baseball was forever changed. One hundred years later, Goldin Auctions and the Babe Ruth Birthplace & Sports Museum will also make history when they hold the largest auction of Babe Ruth memorabilia in the Goldin Auctions Babe Ruth 100th Anniversary Auction.

The auction includes both a Live Auction for 126 super premium items on July 12 at the Babe Ruth Birthplace & Sports Museum in Baltimore and an Online Auction closing on July 18 at www.GoldinAuctions.com. Appropriately, the Yankees will be in Baltimore to face the Orioles that weekend.

Here's a look at some of the unique Babe Ruth lots.

Lot #1 - Babe Ruth's "First" Yankee Stadium HR Baseball- This ball, consigned by legendary sports memorabilia curator Joel Platt, was hit by The Babe on February 14, 1923 during a stadium construction tour for New York Daily News reporters to demonstrate the Stadium's short right field porch - 2-month before Opening Day. Since the stadium had not yet been named "Yankee Stadium," the ball is signed and inscribed by Ruth -- "New Yankee Field Feb 14-23 Babe Ruth." It features a distinctive mark where the ball was struck and is authenticated by PSA/DNA, JSA and comes with a Sports Immortals LOA.

This is one of only two Ruth branded bats from 1918 or earlier featuring "RUTH" stamped in block letters which helps to date the bat as being made before July, 1918.

Lot #40 - The Hand of George Herman Ruth (PSA/DN 9) -In 1934 Baseball Magazine had Atlanta-based Alice Denton Jennings run a thorough character analysis from an inked imprint of The Babe's right hand.

A near mint copy of the July, 1934 edition of Baseball Magazine with Miss Jennings' page and a half analysis is included in this lot.

Lot #57 - 1918 Babe Ruth Boston Red Sox Contract  - The Babe's copy of the earliest known Ruth payer contract. After winning 24 games and posting a 2.01 ERA in 1917, Ruth was given a raise from $3,500 to $5,000 for 1918. This was also the year of the Red Sox last World Series title until they broke the "Curse of the Bambino" in 2004. The 4-page 8 ½   " x 14" American League Player's Contract has been signed on the 3rd page by "Geo. H. Ruth" (10/10), AL President Ban Johnson (10/10) and Red Sox owner H.H. Frazee (10/10). The document is displayed in its own custom museum-quality 10" x 15 ¼" x 1 ¼" red leather bound book. The terms of this contract were in place with compensation modified as part of his sale to the Yankees the following season, meaning this contract was not only in effect for his last two years with the Red Sox, but also his first two years with the Yankees.

The document was originally owned by Barry Halper who purchased a large collection of documents from the estate of Ed Barrow.

Buck Weaver, best known as a member of the 1919 Black Sox asked Ruth to sign a bat to his friend Eddie Maier in 1920. Thorough research shows that The  Babe used this bat during the years 1918-1920, spanning the years Ruth spent with the Red Sox and Yankees. The slugger proudly signed and personalized the bat in black fountain pen: "To My Friend Eddie Maier from Babe Ruth1920." The particular Hillerich & Bradsby center brand is of the "dash-dot-dash" variety, once thought to have only been used during the 1916-1917 period.The bat itself shows excellent game use with several ball marks on the left barrel above Ruth's stamped signature.

Lot #94 - Babe Ruth Single Signed A.L. Baseball from his Last Public Signing (PSA/DNA 8.5 with Mint 9 Signature) - Two months before he would succumb to the ravages of cancer, the Babe made one of the final public appearances of his career.
