I think it was quite common to plate coins with gold for use in jewellery. But since it was not done by The Royal Mint, and the gold wouldn't be worth the cost of recovering it, it's often considered damage.
What does it have to do with the weather, its a gilt plated coin.

English is an evolving language that you or I can't stop.
