How to plan for distribution of some personal possessions?

We've owned a home for 30 years. Over time I've moved a lot of stuff to where we live now, but not some big items of furniture. I need to sell the first home but don't know how to handle the big items which hubby brought into the marriage with him. He made no provisions for giving any of them to any of his 4 kids and I'm indifferent to them (the things, not the kids!) and would just as soon leave them and sell them with the house, we have no place for them here. I do have his POA so I guess I have the right to do that. But I worry that the kids might wonder where the stuff is after he passes. On the other hand I don't want to go through all the bother and expense of moving them to a storage unit near where we live now. I guess I could tell the kids to come & get whatever they want but they all live hundreds of miles from the house and I'm not there very often.
