The 49ers didn't win the SB in 1992... they won in '81, '88, 89 and '94. But there were a lot of players that were Super Bowl winners on the '92 team. If you look at some of the footballs that have a single signature like Montana, Young, Rice, etc. you will see that each ball can sell for up to $400 depending on the quality of the signature and ball signed on.
I have a team autographed ball from the 1992 team (First and second string players and coaches). I am guessing that ball is worth several thousand dollars. You just don't see many coaches autographed items out there... so rarity comes into play there. I would be interested in having my ball appraised too.
You could sell it on ebay for about $300.
The value of the 1964 team-autographed Cleveland Browns white Wilson football in mint shape varies somewhat with the collector's market. This football can sell for as much as about 300 dollars or as little as 100 dollars.
