It is always hard to part with stuff I've been hanging on to.
I had 5 Oh Canada sets that I broke open for a couple coins that I wanted. I had a little fun spending the common stuff. Even people who do not collect coins can see the shine of the fresh ones.
I went to donate a bag of cents, and a few usa halves at the beer store and it turns out the cashier is a collector. I ended up giving her the bag to exchange anything she wants before it goes in the jar.
I took an old dryer apart to use the drum for a firepit and there was a pile of change inside.
