I would keep that old Pfaltzgraf. It is heavier and thicker than what they came out with later. My parents got me a set of Yorktown the Christmas before I got married. Pieces got broken along the way, and my husband got me a new set. Definitely inferior. I’ve now replaced with old pieces from thrift and antique stores.
My husband and I had a set of Grand Marquis(s?), ’til a deer took his out. Deployed airbags and everything.
