In veilstone go talk to everyone I think someone in a house has it and they let you have it but I haven't played in years so sorry if I'm wrong I think that's right. By the way I don't think you can use the coin case to gamble because I asked a friend why I couldn't play and they said the gambling has been stopped because little ones have this game and it is sending a bad message sorry if I'm wrong good luck on your game hoped this helped! :)

In Veilstone City, the house to the left of the game corner (on the other ledge) there is a clown. When you talk to him he will tell you to pick a hand. No matter which one you choose, you will receive the coin case. You must choice the left hand or you get nothing!
I can trade you one if you want.
You buy harbor mail and give it to a girl she will give you a coin case.

It increases the value on the coin.

From the clown next to the massage lady in Veilstone. The clown will ask you to pick a hand. Keep tapping "A" until you get it right.
it will say platinum on the game case...
you get a coin case that's next to the game corner. and buy some coins.
Platinum metal looks like silver but is heavier than a coin. Platinum is equivalent in color to silver. The platinum is also heavier than the silver itself.
5-10-11>> The coin is 1/10oz of pure platinum and the value is tied to the spot price of platinum at time of sale and it varies, as I type this, the coin is worth $179.20
8-9-11>>> The West Point Mint only strikes $100, $50, $25, & $10 platinum coins, no $20.00 coins. A $25 coin is a quarter-ounce of platinum, so if the coin is real, it's value is about $400.00 today.
I can trade you one if you want.
No platinum coins were struck in 1879, the first ones were in 1997
