The nice thing about antiques is that they keep getting older. My consignor bought this "Antique Japanese Cast Iron Tea Pot" during her trip to Japan in 1970. It came with a piece of documentation stating that it was over 100 years old and that was over 40 years ago! She never expected her twenty-five dollar investment would some day be worth $1,175. One bit of provenance can make all the difference between a $10 item and one worth $1000.
