Weight of coins?

[Clumsy Bob]

After glancing through a few books, I still cannot find how much coins weigh?
I figure for simplicity reasons all coins, copper, silver, gold and platinum will weigh the same.
But how much is that? How many coins weigh a pound? 10, 50 or 100.

Thanks for any help,

Bob

Well, that pretty much narrows it down....
