First, condition means a lot. Buying sight unseen on ebay leads to reduced value
I repair antique metalwork for a living. I charge $20 to remove a simple dent in a silver plate pot, The dealers bring me 2-3 a week.
Second, sets bring a premium. Orphan pots are bought by college students and young marrieds, trying to decorate.
Sets are bought by someone who is looking for a 25th anniv gift for their cousin Leon.
Here's a generic set, sans tray for $175
Here's a more collectable set, with tray for $1095 down in DFW
This, I fully agree with. A silver teapot is one of the worlds most useless things. You will spend more time cleaning it than using it, but it is an attractive thing, that you would never have thought about buying retail.
You paid as much as you would have for a movie and popcorn. If you only pull it out on thanksgiving, you will have had more enjoyment than it's cost .
