Need help on value for 3 Sugar Ray Robinson autographs

[LEIDEMEG]

Obtained these three autographs that were in a scrap book, a ringside card, a leaf card and a photo. I have no doubt as to authenticity but not sure what they are worth. I have many autographs but my main interest is baseball. Any estimate on value would be a great help. The cards have small of paperloss on the back from removing them. George L

Nice. Sugar Ray isn't a tough one to get on cards. I have a Ringside. I think it cost me about $275-$300 a few years ago in an auction. The picture I don't know.

I'd recommend having them authenticated and encapsulated by JSA/BVG or PSA/DNA if you want to max the return on them. Otherwise you'd have to find someone willing to take a shot on them which will cost you some in risk premium.
