What would be the most effective way to make an inventory?

Do i make a folder filled with every single item in the game with item Ids? how would i get each item to have a different value? i am trying to start simple with like 5 items in the game so it wouldn't take long to make. i just need to know a way to handle the items and what their values are.

I know that i can save a table of the players current items. If anybody knows a good way to make an inventory please answer.
