Only coin I really miss is one that had sentimental value. My Granddad was born in 1885 and when he passed in 1980 I inherited a little keychain that had a circ. Morgan from his birth year. I was a struggling musician back then (early 1980s) and a couple of years later I had no money or food. I sold it for seven bucks and bought a whole chicken and a 1-pound bag of rice. I still regret that one.
