I think I have a miss-strike or error coin, will this have added value?

If you have a coin with an interesting variation it’s important to check if it’s something that could have simply been caused by mass production (a miss-strike which is unlikely to have any added value), or if the variation could have been caused by human error, potentially making it very sought after by collectors and adding value. It’s important to get error coins verified by The Royal Mint – see the next question below. Find out about mis-strikes and myths in our blog here.
