We have purchased a house that was built in 1804. There are really old items left from over the years everywhere, wouldn't mind selling some of the things if I knew what was valuable and what is just junk. How do I find out? Is there something I should look for that would suggest an item may be worth something? For example there is a chair in the attic with a swastika design on it (pretty creepy, I think thats why it has stayed in the attic).
