How much does an NFL box cost?

Excuse me, could you please clarify the specifics of the "NFL box" you're referring to? Do you mean the cost of a luxury suite or box seat at an NFL game, or perhaps the price of a commemorative or collector's item in the shape of an NFL-themed box? The cost can vary significantly depending on the location, team, and type of box in question. Could you provide a bit more context or detail so I can give you a more accurate answer?
