As we approach what would have been Queen Elizabeth II's 100th birthday, we pay tribute to our longest-reigning monarch with pieces of her legacy that will truly stand the test of time - her coinage (both bearing her portrait, and those issued in her honour). In an anniversary year of this magnitude, demand will naturally turn to these key issues, and so limitation is scarce, and availability can only be on a first-come-first-serve basis. Don't miss your chance to pay homage to our once-in-a-lifetime monarch.
