Rather brilliantly, the designs are the work of a 26 year old graphic designer, Matthew Dent, chosen from an open competition that attracted over 4,000 entries. We wonder if he'll get a Blue Peter badge for his efforts?
The coins all use a heraldic shield as a linking theme – the £1 coin has the full shield, and the rest of the coins feature segments from it, making up a sort of gappy jigsaw puzzle that'll set you back 88p. It's a kind of post-heritage feel.
The new designs will be hitting your pocket gradually during the coming year.
