Need Information on Baseball
 

I have an autographed baseball signed by Ken Griffey Jr. It has the date of April 10, 2000 and below the signature it says 21/400. I can't seem to find any information on this baseball. Can someone shed light on it? Possible value?

thanks in advance,

Lytnup

Well that is the date that he hit his 400th homerun.
I would say that he signed 400 balls like that and you have the one numbered 21/400.
Here is one that says 93/400 $179
