What’s the formula for boosting memorabilia values? How about:

$$$ = Big post-season - past post-season failures + big return after injury – forgotten PED admission + keeping mouth shut and saying the right things

We had heard earlier in the off-season that there was a spike in ARod’s memorabilia value and now we have the latest proof (proof there’s a bigger, richer idiot out there waiting, lurking):

A-Rod’s 500th home run ball is going, going, gone!

The ball smashed by the Yankee slugger on Aug. 4, 2007, to reach the historic milestone fetched $103,579 in an online auction that ended Thursday night.

Wonder how Todd McFarlane feels about the $3 million he paid for McGwire’s 70th HR ball way back when we were fat, dumb and stupid happy.

In other words, just like we are today, only older.
