This is the final week to bid on Memory Lane's auction, which features the only Gem Mint-graded 1933 Goudey Lou Gehrig in existence and ends Sept. 15. The card is graded PSA 10 and is from the collection of Charles Merkel. The current bid is $91,000.

There’s also a 1952 Topps Andy Pafko Black Back graded PSA 8. Since the card is No. 1 in the set, it’s one of the most notoriously tough cards to get in high-grade condition. This one is already up to $44,000.

Next, a Hank Aaron game-used bat that was used to hit his No. 704 home run carried a minimum bid of $5,000. The bat is a Louisville Slugger model A99 and is graded A 9.5 by MEARS, with heavy usage with ball marks and stitch marks “deeply embedded.”

Also, a 1933 baseball with nine signatures, including Babe Ruth, Gehrig, Al Simmons, Joe Cronin, Jimmie Foxx, Ed Rommel and Jimmie Dykes is up to $5,500. The ball is an official American League Harridge ball with PSA/DNA and JSA authentication.

One extremely unique item is an uncut sheet of 1969 Topps Baseball cards with a White-Letter Mickey Mantle near the center of the sheet. The sheet has 132 total cards is at $5,000.

There’s also two killer Yankees team payroll checks, with one signed by Gehrig and the other by Ruth. Both are from 1930 and also signed by Jake Ruppert and Ed Barrow. The Gehrig is already up to $15,000 and the Ruth is at $13,000. Visit www.memorylaneinc.com to bid.
