He already discarded the Money In The Bank briefcase and got a silver briefcase and he walks around with it all the time.
I think it is to add more importance to not only The Miz and Alex Riley but to still act as if the Money in the Bank means something, I think they will hang onto it until The Miz loses his title and/or the next money in the bank
That's not the money in the bank, it's a regular briefcase.
It's holding his case papers in it
