There can be various reasons why you are missing some of your Coins.
It might be because you have accidentally purchased items in the game requiring Coins.
It could also happen that someone else has access to your device (or another device using the same Google Play Games, Game Center, or Facebook account) who might have spent Coins. Unfortunately, purchases made with Coins can’t be reversed.
In rare cases, the game might crash unexpectedly before the saving process has been completed. This can result in a loss of any unsaved progress such as Coins.
