I'm not that old but...

I remember when copper pennies actually were made of copper. And nickels were made from real nickel.
I regret not saving silver certificants when I could. Or putting away silver coins. Should have turned in my paper bills for gold when you still could.

If the date on a penny is 1983 or later, it is made of 97.5% zinc and plated with a thin copper coating.

Wow! I didn't know that. Interesting.

Used to be, banks kept a certain amount of gold to cover currency the bank issued. Not worth the time to rob a bank anymore. Not worth it to counterfeit paper money anymore.

You used to be able to go get a few rolls of half-dollars at the bank and usually find one or two that were pre-1964. Those days are gone, too.

You're old because time is giving you regret. Once you spend most of your energy looking back and start complaining about where the world is heading you're old.
I am old too, but it's slower for dumb people
