ELI5: What happens to the cash my employer seized?

I work as a sales associate for a retailer that does not allow you to accept tips. If you do, and are caught, you will be immediately terminated. I was given a $50 tip by a customer who refused to take it back and would not accept no for an answer, even when I explained I couldn't keep it. I went to my general manager and explained the situation and he told me I needed to turn it in to him or be terminated on the spot. 

What happens to that money? And who does it belong to legally? Thanks in advance!

Assuming they aren't just pocketing it, the money just becomes revenue for the business, like any sale. 

The basic legal principle is that you, as an employee, are an "agent" of the business. Any money you make as their agent is really theirs first, though eventually part of it becomes your salary. If they don't let you get tips, then the money is there's the same as if someone just decided to pay more than expected for some item.
