Postage stamps from the 1800s... maybe other things too.

I have a Clovis spearhead. So at least 10k years old. I also have a huge chunk of petrified wood of unkown age.

A signed photo of one of my Civil War ancestors that my grandmother wanted me to have.

Some 19th C ancestral furniture.

Some leftover kung pao chicken behind the milk that I swear I'm going to eat this week.

Several ammonites some hundreds of millions of years old.
A Cahokia-moundbuilder pot ca. 1000 CE, de-accessioned by a museum.
Some volumes printed in the 1600s.
A Native American basket ca. 1800.
Two Daguerreotypes ca. 1850.
My toenails are getting pretty old too.
