Hey Willy55,
As stated above, the coal will show up immediately after battle that you met the requirements. It will show up in your Rewards tab at the bottom right when you are in port.
Republic Tokens show up in the Armory.

If you want to see what each symbol will give you for each ship, you can hover over the symbol to see the reward!
The rewards are granted immediately after the game finishes.
