I have one such helmet. I want to know what the value of the helmet is.

That totally depend on whether it has been authenticated. Is it a real NFL helmet, a mini, potato chip bowl with a blue star on it, what?

A good way to gauge the market is to watch how they are selling on eBay. That will put you in the ballpark, based on what you have...

Well it would definately depend on the person doing the buying. My hubby has a football signed by all the players from 1992, plus a few extras, haven't thought about selling it though. Whatcha want for the helmut?

put it on eBay and see what kind of offers you get.
