There are multiple ways to narrow down the date of a coin but some cannot be totally narrowed down. Here are a couple of links to look at the differences of the obverse and reverse changes over the years and it would appear to be a zinc cent which helps narrow it down to 82-2008, the rest is just work.... It also helps to just look at different years of actual coins, the differences in the font of the letters and design, both obverse and reverse.
