I recently acquired a 1943 Steel Lincoln cent from a Whitman folder purchased at an estate sale. I immediately noticed that this piece showed no apparent signs of corrosion and had a rainbow like hue about it. After examining it under a digital microscope, the coin showed great detail in the strike and had a copper colored residue. I took the coin to a local assay house, and it came out as 98.08% Fe and 1.92% Cu with <0.10 Zn. The coin weighs 40 grains or 2.7 grams. What do you all think I have here?
