What do you own that’s older than you?
Too many things to list, but a few examples:
My house is older than me, as are (obviously) all the things I've made with wood I've recovered during the renovation process. If I can salvage wood rather than destroying it I do, so I've got a load of fir and cedar that I've recovered stacked up waiting for some ideas for what to do with it.
I have a few textbooks from when my father's schooldays, back when he was in his late teens.
When my wife and I cleared her aunt's house after she died I found a piggy bank stuffed with dimes. I managed to get them all out without breaking the piggy bank and counted them - there was about $15 worth of dimes. Then I wondered how long they had been tucked away at the back of the closet - sure enough they were silver dimes so the $15 in value turned into more like $200. Not exactly a retirement fund but a nice surprise, and of course they date from 1964 and earlier. I also have a few silver dollars I found that date back to the late 1800s although they aren't worth anything like what I first hoped when I saw the dates.
