That is what we should do

Recently, while doing some house cleaning, we unearthed a very ancient looking equipment. And upon checking on the internet, we realized that it is a Vacuum coffee maker. The brand has been washed off but otherwise this piece of equipment seems to be in good shape. We are not sure what to do with it then decided that why not make some money out of it. Without verifying by experts or any checking. We list this equipment for one thousand dollar on the Ebay. Amazingly, within 3 days, the bid has went up to five thousand dollars! I guess it must be some very valuable equipment, but still we honor our word and sold it for 5 thousands and five hundreds dollars….
