In this hobby, I learned 30 years ago to buy my own (antique collectible insurance). There are several companies that provide collectible insurance and it's not that expensive. If you sign up as a "Dealer" it covers any shipping or hauling. They would pay the claim, no problem. There are certain requirements, but if you follow the guidelines, the collectible insurance is the way to go. So sorry for your son's loss. We have all been through it and it does SUCK!!!
