The coins I'm familiar with usually involve a grade to distinguish value-If you could post a picture that would be helpful.
Welcome to the forum Mags. Can you post a pic of your coin? 1879 victorian... hmm, either a 1/2 crown, florin, shilling, 6p, 3p, penny, 1/2p, farthing, 10/- or a sovereign... values vary depending on the grade and denomination you have.
