The Landmarks of Britain coin series from the Royal Mint commemorates some of the most iconic pieces of architecture in the Great Britain. This series is specifically focused on the city of London and many of these landmarks are known to people around the world whether they’ve set foot on English soil or not. The Tower Bridge issue is the second coin in a four-coin silver bullion series that features additional designs of Big Ben, Trafalgar Square, and Buckingham Palace. The Big Ben coin was the debut design issued in 2017.
On the reverse of the 2018 1 oz British Tower Bridge Coin is the image of the iconic suspension bridge from road level looking up at the two towers. The bridge towers on the structure are tied together at the upper level by horizontal walkways designed to withstand all the tension forces the suspended sections between the towers and land exert on the structure.
