Abstract Many of us have pondered puzzles involving a set of n coins and a balance scale, the idea being typically to find the counterfeit coin and determine whether it is lighter or heavier than the others using the fewest possible weighings. Here we take a slightly different tack, but the equipment is familiar: a set of coins and a balance scale that can tell us which of two sets of coins is heavier or that they are of equal weight.
