You should really never let movers handle, pack or see any valuable antique porcelains, clocks, silver or artwork. They usually don't know the difference, and if you bring it to their attention, it will likely get stolen along the way. If it is rare or priceless move it yourself. It is safer in your car. Same with jewelry and furs. Or anything someone would sell on the black market. If it is going overseas..sorry. I like to pack with unprinted newsprint, then bubblewrap, dishpacks and double box with a buffer layer between boxes, especially if you are going to use UPS.
Making a claim against a moving co is difficult and they drag it out. I f they break things in the truck during the move, there is usually a clause that a "professional repair can be made" not replacement. The laws and contract is on their side.
Moving is always difficult and a bad business. Bad things happen when things are stored between moves or transferred to other trucks. Sometimes movers piggyback your things with someone elses.
