Alexandra Gardens, Cardiff 2

The roadshow comes from Alexandra Gardens in the heart of Cardiff, where treasures include a Maori pipe, a book listing wartime spies and a rare SAS medal collection.

Ronnie Archer-Morgan is thrilled to see a pipe by a renowned Maori craftsman, whilst Geoffrey Munn is dazzled by a jewel-encrusted stick pin given as a gift from King Edward VII and Queen Alexandra.

There are plenty of Welsh treasures to be found, including an autograph book featuring a Tom Jones signature and early concert ticket, and Lisa Lloyd challenges Fiona to spot the most valuable item in a group of three pieces of rare rugby memorabilia.

Marc Allum is stunned to see a remarkable archive of First World War-era photographs documenting arrivals into Cardiff Docks, some of whom were suspected of being spies, and militaria expert Mark Smith is humbled by a group of medals and a cap badge belonging to one of the earliest members of the SAS.

Fiona Bruce finds out about the long history of Alexandra Gardens as a war memorial when she meets Simon Weston, veteran of the Falklands conflict.
