I've been lucky enough to get 200 gold once or twice, I get a few inks (blue, green, brown), 50 tokens every so often, and I got a hermit cat and a goldfish for my aquarium from it biggrin
Mostly it's just crummy stuff, but even if it's 5g it's better then what you started with.
I've gotten 777, 1000, and even 10000g, though the last one only happened once. Rare inks like white, orange, gold, pink, or purple also show up. Goldfish, sharktooth fish, and arrow fish are also possible prizes. I've also gotten random clothing items, including Black GETA grip skirt, winter green ocre skirt or something like that, and some pair of boots or other. Not bad, really.
