Eggity: What are the coins good for? I have Over 76,000 and don't know where to spend the coins.
hmm, some people throw away more than that playing high stakes and it cost more than that to level up apparel. you will likely need upwards of a million or more coins to upgrade any apparel you would like to use - if you go into the coin rooms to play.
that said, given you receive 100 coins per level for free as an incentive to play coin rooms - I could estimate or project you should have around 350,000 just from your coin level up bonus maybe less given you did not receive coins for level obtained prior to the coin rooms starting.
many people have hundreds of thousands or millions of coins that started out on flash and wonder where they all came from - and it can be in part from leveling up - you see WGT retroactively issued them once people signed into a mobile device or the new version of the game so everyone should have had various amounts of coins already available to them even if they never played mobile version of the game before.
it would appear - you have either already spent some - or not doing all that well in the coin rooms competing against the coin room specialist with maxed out apparel - where you can feel at a disadvantage.
hang in there - coins will truly begin to feel worthless or have far less value when you get into the hundreds of millions, billions or even trillions which some people have done.
