How much does a coin weigh?

I'm curious to know, how much does a typical coin weigh? I understand that the weight can vary depending on the type of coin and the material it's made from, but is there a general range or average weight that one could expect? For example, if I were to pick up a random coin from my pocket, would it be a few grams or closer to an ounce? I'm interested in understanding the physical properties of coins and how they compare to other forms of currency.
