Derek Jeter is a pretty common signature. Steiner really cranked out Jeters this year and it seems as though the price is softening. Steiner had a few sales where Jeter autographs were below $200... something we've never seen in the past from them. For common signatures I try to get a good inscription, or as in the case of this signed card, a rookie style signature. No matter how many more Jeter signs, he won't be signing in this style ever again.
1924 NY Yankee payroll check signed by Hall-of-Famer Ed Barrow and 2013 HOF inductee Jacob Ruppert. Endorsed by outfielder Lawton "Whitey" Witt.
Mercury and Gemini astronaut Virgil "Gus" Grissom. Really fresh, choice signature.
Roger Maris signed 1965 Topps card with a great ballpoint signature.
Perhaps my favorite of the year. On June 13, 2006, this ball was used to strike out Cleveland Indians second baseman Ronnie Belliard, winning the game for the Yankees and giving Mariano Rivera his 392nd career save.
I haven't been as focused on comics in the past year, but I did add a few ECs to my collection.
And finally, I was happy to add an Ian McDiarmid to my Star Wars collection.
Best wishes for happy collecting in 2013!
