Where do I find the value of a century old solid porcelain sink? We got it from an old old school that was being redone. It has a seal and a pat. stamp from 1906. The thing weights a ton and is in great shape. I'm wanting to sell it and I know someone building a new home that likes old things would love this thing and it's got to be worth pretty penny. Any ideas? You guys have been so good in the past. I thought I would ask while I hunt the net. Steven G. Ogden I'll add pics later.
