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?

It's midweek in Glasgow and Paul Martin's up against antiques whizz-kid James Spiridion. Faced with the choice between a Charles Rennie Mackintosh-inspired doll's house and a statement piece wooden bird cage, the auctioneers must use their saleroom savvy to select the piece they think has the better chance of making a mint. On valuation day, will the auctioneers accept or reject an art deco diamond ring, or pair of signed souvenir rugby balls? It's all to play for - but who will come out on top today?
