A British 1p coin has a mass of 3.56 grams, so 1 pound (currency) worth of pennies (that is, 100 of them) would have a mass of 356 grams. At normal Earth surface gravity this would correspond to a weight of roughly 3.49 N, or 12.6 ounces.If you meant "how much does a pound (weight) of pennies weigh", then I'm sorry, if you don't know that a pound of pennies, or anything else, weighs a pound then I don't think we can help you.
A kilogram is a measure of mass, not of weight.
