I guess it was 10 years ago now that a 1901 VF Indian head cent came rolling out of the automatic change machine at my local supermarket.
About 4 years ago wandering the Spectrum in Irvine, CA. I found a Mercury dime 1943 G. Spectrum is a large complex with retail stores, movieplex 10-12 movies screens, bars and restaurants.
I found a silver dime at the Coinstar in reject bin. I also bought a silver dime for a buck from a lady making a deposit at Coinstar. She thought I was nuts to pay a dollar for a dime.
