Display of collected coins?

Question

Unity

Good evening! Please tell me, when picking a coin, you need to display exactly how much I picked up (for more details - there is a coin prefab, a trigger, when picking one coin, a random number of coins is credited; For example, picked up a coin - +7 was displayed in the picking place - and disappeared). How, in the place of coin selection, to display the number of coins, how much Random generated, roughly speaking? Thanks in advance!
