I have found an odd looking 1989, appears to be missing the copper plating. Can anyone confirm if I am correct. The weight is 2.49g.
The cents struck from mid-1982 to the present are struck on planchets made up of a solid zinc core (with a trace of copper) that are plated with pure copper and weigh 2.5 grams.
What's the approximate value of my coin if it is the zinc core? are these errors rare?
