An Item Granter could work and use the Grant Condition - Only if Not Owned, but I’m not sure if that applies to any object of the same type or specifically granted by that device.
If it’s only a coin, the Collectible Object Device does just this with the option of Consume if Collected By - Self
But then this is limited to the 20 or so different objects in its list and I think they are all non-consumable and the coin is not the same as the currency coin used by vending machines.
You could also link a collectible object collection to an item granter to grant currency coins when player picks up the collectible coin.
