Gardens inc 4

Ok so on the map for each level if you hover over them, it shows what trophies are available (mole, chest, coins). Some of these maps, I have collected all visible coins, nabbed the mole a few times as well, and am still not getting a check mark for the coins when completing the level. Is there a certain dollar amount you have to get or what am I missing? Exampe... level 42 I just finished. No coin trophy after getting all coins I could find.
