Having gone through this exercise recently, silver is typically only valuable if it’s not plated and then only for the metal. Unless you have some really special pattern that someone else wants, it will be melted down for other uses.

Old China patterns are very hard to sell as well. Younger people have no interest in things which can’t go in a microwave and need to be hand washed.

And - having also gone through it - there are legitimate lead concerns with old china. I sold my family's mostly for that reason. Kept the silver for emotional reasons but still haven't used it yet. Probably a sign there.
