Thank you Lubna for you valuable question and also thanks to Amrut for his great detailed answer .
I think also the idiom although simple and direct , there is slight shadow of philosophy in it .
I think the idiom implies in the cases where there are only two possible conditions the existence of one means the absence of the other there is nothing in between .
The coin when thrown up it is either picture or text when settles down, but when it is still moving in the air it's condition is a mixture of picture and text can't be considered in real world because it is still in the world of probability.
So the idiom must be used with much care for example can't be implied for colors like black and white because there are many degrees of gray color in between .
I hope have been able to give precise definition , Thank you Best regards

knowledge and experience are the two sides of coin.

to put it into a simple answer "two sides of the same coin" means two different sides opposing each other..
In a project if you can gain some extra benefits by hiring new employees its the one side, on the other side you will have to manage more people and train them and bear some new admin costs which may be are not suitable yet.
so when ever you take strategic decisions or on lower level you should always look on the both sides and then decide which way to go after evaluating both by comparing its weight in comparison with other side.

It means a person, subject or idea can be viewed two different ways.
