The Sims and the rings in Sonic (if those count as money?)

This is a toughie - most games just have spinning coins anyway...

In Top Hunter they had these big gold coins...
Pang... Coins...
Diamonds in some games...
I think... In MAPPY they had a lot of monies and cash,

tough one. Could make an interesting idea if you can pull it off.

Asked my family, heres the list they gave me

Studs in lego
Rings in Sonic
Simoleons in The Sims
Bolts in Ratchet and Clank
Coins in Mario
Rupees in Zelda

will try to think of more later. :D

Bottle Caps from Fallout
Chocolate Coins from Viva Pinata (Not sure how recognizable that'd be though)

And this isn't very unique but I'd think very recognizable. Copper, Silver, and Gold from WoW

these are great. thanks.
can't believe i forgot sonic.

Yes, bottle caps from Fallout was the first thing that came to mind. Makes me want to play some Fallout 3 again!

bananas from donkey kong man ! and something from mega man

CP from Halo: Reach (more like experience but its used to buy armor)
Gil from Final Fantasy (all of em)
Angelic Souls from Bayonetta (probably my favorite currency from any game)

also, bottle caps are the best in my opinion, really recognizable if you do them right.

Meseta from Phantasy Dancin Online
Zenny from Megaman and other capcom games like Monster Hunter
Red and Blue Orbs from Devil May Cry
Pride Souls from Devil May Cry 4
Essence from Ninja Gaiden series
Pokedollars from Pokemon
Nameless "Points" from various series
Yen, basic Japanese currency, used in various games (Yakuza)

Glowy bits of souls from Demon's Souls?
