There is a company called Replacements Unlimited that buys collectibles as well as china and silver and resales it to people who need to complete their pattern or replace a piece. You can send them pictures for a quote. I have bought items from them before to replace broken pieces. http://www.replacements.com/collect/manu/h.htm

We just moved my MIL into a retirement community and had an auction company come out and give us a price on the items remaining in the house. LOTS of figurines and assorted glass and crystal pieces along with some furniture. They would take everything and auction it for us for 35% of the sales or just give us a flat amount, which is what we did. It ended up being around $1,000. We are going to take one set of china that none of the children want to Replacements Unlimited. Doing this really makes you want to avoid accumulating stuff.
