'Hardcore Pawn' Star -- Makes Offer On Seahawks Football ... I'll Outbid EVERYONE!

The star of "Hardcore Pawn" is gunning for the famous game-winning football from the Seahawks vs. Packers game ... and he tells TMZ Sports he'll CRUSH the $20K offer that's already on the table.

Les Gold tells us ... the pigskin that Seattle WR Jermaine Kearse launched into the stands after catching the winning touchdown is an instant collectors item -- and he's dead set on getting it.

The man who caught the ball, Scott Shelton, has already received a $20,000 offer from a sports memorabilia dealership -- but Gold says he's ready and willing to smash that number.

"Whatever the highest offer, I'll offer a thousand more," Les tells us, "Offer 25K, and I'll offer 26K. That ball will be in my shop."

So, why's he so set on getting the ball? Les says it's an iconic piece that could double in value over the next few years.
