What's the oldest heirloom you own, or have heard of anyone owning?

My grandpa’s pocket watch, circa early 1920s.

That’s it.

My g-g-g-grandmother’s tambourine from the late 1800s - she and her husband were Salvation Army pioneers in East Anglia (UK).

Unfortunately I mislaid it some years ago (although I think it may be in my mother’s loft) … and I distinctly remember inscribing it with the legend “The Osmonds” circa 1972. :smack: :o
