Where are my coins???

After you receive 50 coins in a day you stop getting more. When those other two come back check if you get coins. Since, it was over 8 hours ago, you'll likely get all 50 from one of them and the other will give you 0 coins.

Note: I'm NOT sure if they are using the 21 hour timer to equal a day like they used to, so your "daily" bonus might occur in the middle of the day and be counted towards yesterday's total.

Sometimes you have to reset the game to see the coins show up. Happened to me a few times.

Check your journal. If they were kicked from the gym before midnight, any time that they stayed counted for yesterday. Not for today.
The coin limit resets at midnight, your local time. Exactly the same as the first catch or first daily spin
