Assuming the coins are all dated 1965 or later, they weigh 1/5 oz. each so grab your calculator.
If any of them are older than 1965 they contain 90% silver and are worth at least $2.75 each, possibly more if they're old enough. You'd have to sort through them.
IMPORTANT: Do NOT take them to a CoinStar or similar machine for redemption. Those machines keep almost 10¢ out of every dollar put into them as a "service fee". A number of banks will count and redeem coins for free or for a much lower fee.
In any case you'd need to sort out any silver quarters because you don't want to turn them in for 25 cents each!
