This week, Paul Martin's in Glasgow, taking on his youngest opponent yet, rising star James Spiridion. Across three rounds, Paul and James must choose the treasures they think will make them the most money at the end of show auction. On valuation day, they compete for a watercolour of a Glasgow tenement, an RAF brooch, a shipyard painting and an arts and crafts planter. Who will pick the most valuable items to take to auction?
