At $2m, this is the world's most expensive piece of football memorabilia... A Houston Oilers helmet signed by legendary 1970s coach Bum Phillips and several players achieved $2m at a recent charity auction, making it the most expensive piece of football memorabilia ever sold. Phillips was coach during the Oilers' most successful period, when they reached two successive AFC championship games between 1978 and 1979.
