Good evening. This coin appears to have raised areas which look like numbers and or letters. Especially on Lincilns face, shoulder and in the fields on the obverse, not to mention the color variation. It weighs 3.15 grams. Just looking for some knowledgeableinsight.......
@skip, I'd rely more on the weight than the specifics of coloration to guide your thinking on the metal composition. Who knows what sort of chemical or environmental exposure this coin has endured over nearly the last 50 years.
