[QUOTE="Clawcoins, post: 3695118, member: 77814"]the "doubling" you see on the 8 is from split plating. During minting the 8 micron thin layer of copper is stretched and rips. Thus giving the illusion of doubling. Under the 8 micron thin copper plating is a solid core of zinc. The white stuff you are seeing all over your coin is that zinc leeching out. The other bubble type things you are seeing is zinc rot. The zinc is rotting underneath and taking the copper with it. And maybe grease filled die on Rev in the (State)"S of A"(merica) area. [ATTACH=full]990314[/ATTACH] [ATTACH=full]990319[/ATTACH] Zincolns are notorious for split plating, all over the place on both sides. Also seen on the right of the Memorial. Zincolns are also known for single squeeze hub doubling. Which is normally fattening of the letters. I don't really see that here. Plus the condition of your cent would reduce it's value to face anyways.[/QUOTE]
