You're making a pretty big claim there. Mostly, boxing gloves come in black, red, blue, and white. Some brown, and I know there are some pink lines out now. Hard to assemble much of a ranking system that way. And why would you? It'd get expensive pretty quick, buying new gloves every advancement. As others have said, the Golden Gloves are the top amateur competitions -- not a club based ranking. None of us have ever heard of a ranking system like that in boxing. Sure, fighters are "ranked" as in who's better than whom, based on records, mostly, and fighting reputation a little. But that's not a "you're a white glove fighter until this happens..." There are also some kickboxing schools with ranking systems that they've developed -- but those are typically belts, like in martial arts.
So... can you provide any support for the idea that there is a boxing club out there with ranking like that?
