There are 3 platinum coins I know how to get without spending any money.
1. Beat rod six times with the black tornado 2. Beat rod six times with the dark hurricane 3. The last way is kind of diffulcult. You must give all the lengendary items to that guy in the drink shop. He will give you a new option called ''todays special.'' If you give him monsters about 20 times ore so he will say he used them too much and he will give you a platinum coin.
Its really simple you just hide behind that tent thing and when he goes to hit you use rapid fire ore if he appears stunned run all the way around and slice him in the back. it works really well when he knocks the tent over with that giant hammer the black tornado. Because Mint can jump over it and jump kick and knock rad over.
