Very, very little. All pennies made since 1982 (some 1982 coins are made out of a 95% copper bronze alloy, others are copper-plated zinc) are copper plated zinc and only contain a very small amount of copper. Since this isn't an alloy and it wears off during use, it really isn't possible to calculate just how much copper is in there, but suffice to say it isn't much at all.
