I would have to think these are replicas. A real title belt that sat on the waist of a world champion can generate up wards of $10,000 or more depending on the champion.

I think I read some where that Joe Louis title went for something like $50,000 at an auction about 30 or more years ago.

It is not so much the title as the fact it sat on the waist of a champion. Anyone remember Raging Bull when LaMotta sold his title belt and thought the jewels were all that they wanted then he broke the belt up to get them out. The guy offered him like a 1/4 of his first price.
