Itemise your figures, photograph them, Insure for REPLACEMENT Value. Bigger Collections will need to have an inventory supplied to insurer. Everyone's insurer's will be different. Shop around.

To point out the importance of insurance....our CFO refused to put security screens on sea containers converted into tool sheds. (containers fitted with window, air con, shelves etc)

The $220 we saved on not putting them on cost us $1.5 million in equipment theft. The insurance report concluded the containers weren't secure. CFO was fired. (which i was/am secretly happy about!)
