Heirloom...? Precious....definitely. My mother's dishes...they are a beautiful set that includes both a teapot and coffee server. I don't ever remember a time they were not around....I think they were given to her by a relative as a wedding gift. We had "everyday" dishes, but these dishes were always used for Sunday meals, holiday and other celebration meals. She gave them to me the first time I hosted the family Thanksgiving meal. I treasure them so much, and have gotten many, many compliments about them over the years.
I have had them now for over 46 years.....and, if she got them as a wedding gifts they have been in the family, possibly, more than 75 years. It is amazing nothing from that set ever got broken.....a miracle really.
