How do I click/tap on object without effecting those below?

I am working on a game, in which the user is to tap on the screen to win the game, as well as tap on coins to collect these. The problem I'm having is that I when the user taps on the coin, they are also automatically tapping on the screen. I found a small solution for desktops, by using "cursor over object" rather than "object clicked", however I need an equivalent or similar for mobile devices.

Try:

Touch| On tap gesture

...Touch| Is touching Coin -> 'do something with coin'

...System| Else -> 'do something where only screen is touched'

Thanks Worked perfectly
