Multi Autographed NFL Footbal - Brett Favre #4 & buying More

Product Name: Multi Autographed NFL Footbal - Brett Favre #4 & buying More
This was in my uncle's collection that I inherited. There was no COA that I could find, but his filing system wasn't the best so may have gotten lost. I know that he had been mailing items like footballs to be autographed so this might me an example of this. Or he may have gotten it signed personally as I know he had gone to some games or signing events. He was also buying items off eBay. There are several signatures on this ball, the most prominent being Brett Favre. The others I haven't been able to identify and sadly some others are no longer present as they've faded. I'd considered sending it off to PSA but I'm not buying ready to get into grading/certifying items just yet. Feel free to make offers on it, as well as anything else I have posted.
