I don't personally know any coral belts, so I don't have any direct experience with this, but I would suspect it works the same with them as with anyone else giving private lessons. There's no standard price for a private. It's a combination of what that instructor chooses to charge plus what his or her market will support. Individual schools or maybe even certain associations may have a standard, but there's nothing universal across jiu-jitsu.
