This is a great penny keychain that makes for an awesome anniversary gift, engagement gift, or a gift for various other occasions! This lucky penny key chain will be hand stamped with initials with a heart stamped around the year of the penny and then the rest of the date in numbers off to the side of the year of penny. We use a much different process than traditional engraving, which only carves a light groove into the metal. Our products are all uniquely stamped by hand with a hammer and steel stamp, which is a more forceful technique resulting in a much longer-lasting finish. Because our products are not made via machines, it should be expected that reasonable variations will occur; these only contribute to the uniqueness and quality of each hand-finished piece. Copper will tarnish to a natural aged patina. This is normal. If you would like to keep your keychain polished, please use the enclosed complimentary polish pad. Thank you for ordering from PickityPick, we look forward to creating a one of a kind item just for you!
