You have to talk to Judd after winning some, and it resets everytime the maps are rotated. I think the max he'll ever give you is 1400.

THANKS! I noticed the counter resets after every rotation but I never got those coins. Next time I'll return to the plaza before switching off and try talk to Justino, but I got more than enough coins.

Ha ha ha, bless your soul!

Maybe I should go on a spending spree and see how much gear those 100k gets me

Even when you get all the weapons and gear, there's still the adding of slots to each gear piece that doesn't have 3 already, and then you may or may not want to try for a different ability set on some of them. 30k for just one is not cheap, trust me I'm broke!

Had to google that. That option is only available when you reach level 20 (I'm getting there, just three more levels).

Plus in the future we'll have the festivals where we can win those shell things.
