According to research conducted by specialist insurance broker Stackhouse Poland, most collectors are inadequately insured.
The research suggests that 90% of people base their contents insurance on out of date valuations or estimates with accurate information or advice.
Director of Stackhouse Poland Keith Hester said: "As collectors' items increase in value, it becomes more and more important that people maintain current and favourable insurance policies. Regularly updating the estimated
value of possessions is crucial, especially in markets where a collection's value increases dramatically over a short space of time."
