HOF RC Boxing List - WTB and looking for suggestions

1982 Panini Marvin Hagler
1986 Panini Mike Tyson (Italian version)
1986 Browns Boxing Evander Holyfield
1986 Browns Boxing Pernell Whitaker

I have 1989 as the cutoff for this list, but very open to considering others that I may have missed that should be on here, up to a max of perhaps 50 cards. While I have a few of the above, I'd be interested in buying the others, and would love to jointly start an SGC or PSA set registry for something like the above if there is interest and agreement on specific issues. I would love to hear suggestions and tips from the real experts here, and look forward to learning more!
