A silver dime
After being rejected twice by Coinstar (which, by the way, now generates Amazon gift certificates without exacting a fee!) I took a closer look and realized this wasn’t your average dime. Something about it just looked and felt different—almost fake. According to Wikipedia, from 1837 to 1964, dimes were composed of 90% silver and 10% copper. Since 1965, they’ve been composed of 92% copper and 8% nickel. So this is one of the last silver dimes intended for actual circulation. Neat.
This is also a nice demonstration of the macro abilities of the Pentax DA 35mm lens. Taken freehand, with manual focus. The only cropping I did was on the left and the right.
