Did a search for Jesse Burkett and came across the current coaches' corner joke of an auction.

The loa here is from rareandsigned.com. Never heard of them, but this is definitely not a legit Burkett (needless to say). They also certed the most rcent Josh Gibson signed baseball and so on and so forth.
Just wanted to throw that info out there, for whatever it's worth. It's gotta be worth more than the Burkett in the link.
