John,
I have a similar cent, I think from 1995 (I don't have time to dig it out right now). I have a question about the reverse. What does the excess metal look like in hand that runs over the 2nd A in America to the base of the Memorial? Could that be copper?
The one I have has similar raised metal lines that look like they could be copper. It made me think it was plated but the copper was removes post-mint.

I thought the excess looked like wire welding splash. Perhaps some arcing? Looks burnt at the FG.

What would a lightening strike do to a zinc penny? Vaporize the copper?

A lightning strike would not only vaporize the entire cent, but everything around it as well. I have seen three foot diameter craters, eighteen inches deep blown in creek beds (six inch river rocks, gravel, and sand) from a lightning storm in northern CA (we had over 20 strikes within 300 feet of our campsite). I once helped reapir an EBS radio that had been struck and over 100 feet of copper wire from the antenna to the transmitter was nowhere to be found. a coin lying on the ground well away from the point of entry might get some stray current that could cause damage but I don't think it would look like this cent (too "clean").

Yours looks like it has some luster (shine) to it. Does it? Just curious. Mine has absolutely NO luster at all and not even a hint of copper color that I can see anywhere on it. Mine is also rough to the touch, like no plating was ever on it, or it was completely removed off the planchet. Any "shine" I see at all is more like matte zinc color points showing through just a very dark surface. The 1943 Steelie someone sent me recently is a bit lighter coloured (light charcoal gray) than my coin (medium dark charcoal gray)

No luster and it feels a little rough. John1

Yeah, lightning is too extreme but the welder in me still says electric arc.

So sounds like your coin isn't plated either then if its rough and no luster. Never got plated or someone removed it. Curiouser. Was there some special science project in 1995 messing with the newest pennies minted to experiment I wonder, then released, like a message in a bottle and then watched out for any news about any being found? The great mystery of the Penny MIA Plating.

What is the size of it in comparison to a normal cent? The edge is very suspect and strongly indicative of PMD. If a welder was anywhere near this coin it would be an unrecognizable lump of metal, the melting point for zinc is a lowly 787F.

Normal size. If it wasn't for the odd edge I would say it was definitely PMD, but the edge has me puzzled.The edge is sunked in like a clad coin that has been dipped in acid and only the copper got eaten away. John1

Mine is normal size too and the rim/edge looks EXACTLY like yours does.

It weighs too much to have had the copper removed or never plated unless there is something replacing it. A copper plated zinc cent should weigh 2.50 grams, which is what you said this one weighs. Without the copper (2.5% of the total weight) it should be 2.4375 grams, which a good coin scale should be able to differentiate.

No, it does not necessarily weigh too much. A scale that only measures to 0.1 grams will weigh a range of 2.45-2.54g as 2.5 grams. The cents also have a tolerance of +/-0.1 grams, I personally have recorded Zincoln weights of 2.42-2.57 grams on a very accurate analytical balance.

With that being true, what non-damaging test can we use to tell if a cent is missing its copper? If someone overplates a normal copper cent with an extra 1% of zinc, can we tell that it was done without doing any damage to the coin? Can you turn a normal coin into one that looks like it is missing its plating without being detected? The Heritage auction archives only have a few unplated cents but they sold for $23 (ANACS 1993 MS62 partial plate, some copper showing) to $70 (ANACS 1989-D MS64, no visible copper). Might be a cheap way to make some money!

The area next to the rim is an area to check. That is is where I've seen copper on faked ones before.
