Need help deciding where to send this


New member
I have a die cast racing car that I got from a drawing that I won a few years ago. I believe it is a 1/24 scale from Homestead (Ford Championship Week) in 2007. I want to get it certified/authenticated because it is signed by Carl Edwards, Matt Kenseth, Dave Ragan, and Greg Biffle. Which service do you all recommend for something like this?

Any help would be appreciated.
