1983 Topps Vending Case
 

I have a chance to pick up a 1983 Topps Vending case - 24 500 count boxes. How much would it cost to authenticate the 24 boxes, or would I be better off keeping the case intact?
I don’t really collect this kind of thing so would be looking to resell.

Thanks

Contact Steve Hart at BBCE. He's probably busy right now, with the National going on, but he's the one who would authenticate and then wrap the boxes as "From a sealed case" to give them the most value.
He charges based on the sale value of the items.

Thanks. I will contact BBCE and see how it goes.
