[QUOTE="Vitagen, post: 288093, member: 10636"]I believe this is an ACTUAL error, BECAUSE, when zinc burns, it almost always becomes very rough and irritated. For a science expirement, I've placed both a 1990 penny and a 1982 penny (more copper) on a torch and both came out completely different from those original photos. The 1990 penny was completely melted into a ball of metal within seconds (seconds!), while the 1982 penny didn't melt as much, but it broke apart on the rim and molten zinc spilled out. Zinc obvious melts at lower temperatures than copper, from what I saw. Still, this may not be true, but it was for the expirement I did. I'd have to melt 100s of pennies of both pre-1985 and lower (correct?) and from the 1990s to get an accurate result based on average. Still, it's possible the penny originally depicted in this post was melted on a very hot burner. An open flame burns different than a heated surface sometimes. That is, one is a literally exposed to open flame AND heat, while the other is only exposed to heat. The only problem I have with the burner is that this penny's luster appears to be the same on both the normal surface and the damaged surface. Could have possibly been re-plated, but I just see some of that "authentic grit" and "tone" on it still...so I'm going with authentic. Besides, that missing chunk from the obverse is a VERY CLEAN cut. Hard to produce such a clean cut by burning the coin, because a burn of any type would also melt the surrounding details EASILY. And tooling the coin would leave scratches and other obvious clues. Polishing the cut area would also fail to reproduce the authentic luster, because that would only leave a mirror in place of the cut. Though the reverse looks a lot closer to have just been burnt with a torch, make sure to look at the rim around there as well. That's madness that the rim still remains! A torch would 99.9% of the time, Melt that rim as well...no question. Either this is a REALLY good fake, or just plain...not a fake. How's that?[/QUOTE]
