Condition is everything, Sally. If it is fairly worn, it will be worth very little. For it to be worth more, it would need to be uncirculated (or very nearly so) in which case it could be worth a few 10's of pounds. If it is a Heaton penny (small H to the left of the date), it will be worth more than a standard penny.
If you can post a picture, one of the penny boys will be able to give you a value.
