My Dad lived through the Great Depression. he was always very frugal. I was taught; "Take care of the pennies & the dollars will take care of you!"
I will stop to pick up a penny.
I use change if I have it in my pocket. Otherwise,, daily,, when I get home,, I have a few jugs I place it in.
Often,, I find "collectable" old coins. (I was a serious coin collector decades ago,, now just mildly so.) so when I get a jug full, I start rolling the coins. When I get a few hundred dollars worth,, I turn them into bills, and stash them for emergency stuff.
I also metal detect. And coins are a common find. Those get cleaned & saved as well.
Just in the past week,,just by looking,, I've probably picked up 20-30 coins in different places. Mostly pennies,, but a few other coins as well.
I use cash as much as I can so I get coins often. I like getting them,, as occasionally, I do get silver ones. Anybody checked the price of silver coins lately? The young kids at many places do NOT know the difference,, so I just smile when I find any in my change. I have also been known to get old coins in change, only to see the cashier has several in their drawer. Guess who asks for "change for a ,,,,,,,,,,!" About 2 years ago,, I got several wheat pennies like that. And one of them is worth about $40-$50 bucks!
Yep,, I take care of my pennies,, and it does pay off! Thanks Dad!
