What is a 1p shield on a £1 coin?
I have a £1 coin with a strange marking on it that says 1p shield. What does this mean? Is it some kind of special edition or variety of the £1 coin? I'm curious to know the background and significance of this 1p shield marking.


What is the green on coins?
I've noticed that some coins have a green color on them. It's not like the regular metal color of the coin. I'm curious to know what this green substance is and why it appears on coins.
