A normal batting helmet weighs about 3 lbs, or 1360 grams. It is made mostly of ABS plastic which has a density of 0.9 grams/cm3, making the helmet about 1,500 cm3. Gold has a density of 19 g/cm3, so a solid gold helmet would weigh 28,700 grams or 63 lbs. Willie must have some amazing neck muscles to walk around with that on his head.
