There are three answers here: return both, keep both, return the bad lot and keep the good one. Keeping them both. IMO, is an intellectually inconsistent answer. A mistake in your favor or a mistake against you are flip sides of the same coin, so the answer should be return both if you are bothered by the idea of getting an advantage. If it doesn't bother you, then return the one that disfavors you and keep the other one.
