The lucky Irish coin is cast from an original old 1940 Irish Threepence or "Leath Reul". It features the Irish hare, a mystical animal said to bring luck in times of change. This unique Irish design is your own good luck charm, and a reminder of Ireland. The hare is a symbol of mystery, positivity and prosperity. She is also linked to the moon and is a symbol of feminine power. It is believed that people who see the hare as their spirit animal are considered sensitive, artistic, and ambitious. Wear yours as a lucky talisman every day. The Irish harp and the words éire 1940 are featured on the reverse. This is a sterling silver copy cast from a real old 3 pence that I found in a Galway market. The silver is then hard gold plated in 18ct gold. The solid gold version is cast from the original coin also. The original coins were made in nickel, they ceased to be legal tender in 1971. My coin is the exact same size as an original old 3 pence at 17.7mm diameter and 1.9mm thickness. Materials: Gold Plated: 18ct hard gold plating over sterling silver, on an 18 inch Gold filled chain.Solid Gold: 9ct gold on an 18 inch 9ct gold chain. Solid gold necklaces are made to order, so please allow 5-7days for yours to be shipped. The solid sterling silver version is available here. Please get in touch if you would like a longer or shorter chain.
