'Hardcore Pawn' Star: 'Everyone's Trying to Sell Their Muhammad Ali Stuff'

Got Muhammad Ali memorabilia in your house? Good.

Think the fact he died is gonna make your collection worth a fortune??? Think again.

We spoke to "Hardcore Pawn" star Seth Gold -- who runs some of the most famous pawn shops in the county -- and he says his stores have been bombarded with Ali stuff in the wake of his death.

Gold says everyone thinks their Ali stuff has rocketed in value -- and they're asking for insanely high prices.

Ali stuff is highly valued already -- and there is a higher demand -- but Gold says his death won't double, triple or quadruple the prices on things like autographs, pictures, etc.

Check out the clip ... especially if you do own some Ali stuff -- Gold has some great advice.
