In my former life, I worked in the rail industry, and one year I was holed up in a derelict office where I led a small project team. One of the members was named Andy, and he made a nice side living selling railway memorabilia (or crap as I preferred to call it) on eBay.
I had an old Trainload Coal tie pin, and he wanted to buy it off me. It had been given to me when I joined as a sweet 16-year old. Other than holding my tie in place it had about as much use to me as rescinded currency.
"You can have it," I said.
“I would have paid you £10,” he replied.
