I think that the ball at the below link is fairly similar to yours. It isn't quite as bold but it also doesn't have the fading spots that yours does. This ball sold just a few months ago for $8,000. Buyer paid $9,600 with buyers premium, and if seller was able to get a 10% sellers commission, ended up with $7,200 in pocket. Yours has the added bonus of being an Official American League ball. So anything in that ballpark, but hopefully north of $7,000, would be a fine private sale offer I would think.

Hope it turned out well for your needs.
