I think, somewhere, I have a British penny. My BIG regret is that I didn’t keep a Pound Sterling when I was at Heathrow in 2004. I used it in an Interwebs machine and it was the last one I had.
I collect odd coins from my travels, but I’m not a true numismatist. I keep the ones that mean something to me.
We still have the pottle, but we call it a half gallon...
