Why is a 1982 penny rare?

Could you please elaborate on why a 1982 penny is considered rare? Is it due to its limited mintage, specific mint marks, or perhaps a unique feature that sets it apart from other years? Are there any particular collectors who seek out this specific year's penny, and if so, what drives their interest? Additionally, what kind of value does a 1982 penny hold in today's market, and how can one determine if they possess a truly rare version of this coin?
