Hey Tex, I will have to go thru this same shit with my parents. They are in their 70's and their house is an antique show room. We are in SW Ok and I know from around here what you have to do is advertise, advertise, advertise, far and wide when you get ready to have the estate sale. Make sure the auction house publishes names for the various items. Collectors like to know what is for sale and if it is worth their time to drive.
People around here and collectors will drive across the state for a good sale. As one poster already said be ready for some surprises when things sale. Some things will go low that should of brought more while other small items may go high if that's what is collectible at the moment.
I would have that German mold appraised and that tool chest you like so much, if it is real, might be the most expensive item there.
