I found a penny that is silver colored (zinc) on the obverse and is not struck, completely blank. The reverse is copper coated and struck, it looks like a normal penny on the reverse. From the design, Lincoln Memorial, it has to be from 1982 to 2008 (zincoln).
I'm not able to find any info on this type of error on the web. I was wondering if anyone has heard of this and could give me some insight as to what it may be worth?
