What does the $ mean in the "Trainer" section of Gen 3 saves?

[Kishuna]

I have searched google, the FAQ, this forum, etc. for it and can't seem to find the answer.

Next to TID and SID, there's a $ section. What is this for? Is it important or something I can ignore because it's not in future generations? I'm trying to recreate one of my old save file's OTs using a Dumped Gen 9 Pokemon that came from the original Gen 3 game, and this is the one section I can't figure out.

It's just how much money you have in game?
