The Meaning Behind a Coin: In the US, finding a one-cent coin - or "lucky penny" - is believed to bring good luck. Meanwhile, many Europeans customarily give religious coins or tokens to people they love. The coin is perceived as a symbol of fortune and is given with wishes that it will bring luck and prosperity to the recipient. The Meaning of the Sealed Coin: A coin with a key motif is sealed within the Rook. It is a lucky charm that unlocks the door to happiness. A keyguards the entrance to a house, and as it opens doors, it symbolizes the health and prosperity of a family's home. A key may also serve as a precious charm, unlocking the heart of one's beloved.
