George I 1724

While searching the loft came across the following coin, have found the following information on it and have checked the pictures to the coin and found it too match.

George I farthing, produced 1724. On ther reverse there is a die break as a small dot under the first I and another brrak as a much larger dot under the space between the N and the I.

Can anyone give a rough indication to what it may be worth - the coin has been kept in a box has very little wear on the coin and all features are still in tact and clearly visible

Many Thanks
