Firstly, these are the ones for which footage is long sought after but not extant as far as we know: Ali vs. Witherspoon Mayweather vs. Morales Golovkin vs. Kovalev Mayweather vs. Whitaker Spence vs. Broner Klitschko vs. Klitschko Mayweather vs. Spence Lewis vs. Tyson (as teenagers) Liston vs. Foreman Crawford vs. Bradley I'm sure there are more holy grails out there (which I'll be kicking myself about for not remembering, no doubt), but these are the top ten I could compile after an hour or so's trawling online. Any seeing the light of day would be massive finds. Here are some that folks may not realize do exist: Pacquiao vs. Khan Inoue vs. Tanaka Golovkin vs. Mosley McCallum vs. Hearns García vs. Maidana Valero vs. Morales Mayweather vs. Spadafora Porter vs. Mosley Holyfield vs. Tua Durán vs. Benn Chávez vs. Mosley Haney vs. Stevenson Toney vs. McClellan Barrera vs. Quigg Pascal vs. Beterbiev (note: in some cases it may be only a minute or two - and in many, is low quality - but something > nothing) Looking forward to growing out both lists and hopefully scratching a few off the former. Videos of the latter below.

Marc Ramsey has a strict no filming sparring policy. Well, apparently not as strict as we were lead to believe.
There's footage of Ali sparring with Witherspoon in the 'Muhammad and Larry' ESPN 30 For 30 documentary.
There's Klitschko vs Klitschko sparring, too, but they take it very easy on each other. Just go through the motions.
Yeah, but there were more intense sessions that Wlad referred to - in fact, they got so heated they had to agree to not spar anymore. Those are the ones I wanna see.
