With insurances of any kind so much depends on where you live. Example is auto insurances are based on statistics of location, age, marital status, sex and probably the color of your shoes. With coins I would suggest if you live in a large city invironment where crime is an issue, best listen to what has been suggested already here. Get a large safe, keep your valuables of all kinds in there and say as little as possible to insurance companies. The less someone knows what you have of value is the way to go. Try to remember that with any organization that has your informatin on their computers, there are people that can access those computers and people are people.
