Besides being harshly cleaned, wear can take off some weight. Usually it's acid that reduces the weight. People just love to experiment. There are such things as "minted on a thinly rolled planchet", which would be a good error. I doubt this is worth anything. Photos of the reverse and edge, along with other coins for comparison can help. There is a weight tolerance of +/- .13 of a gram for cents. Your coin is under that weight, but with just a photo of the obverse it's difficult to determine anything. (Except that it has been cleaned, the color is an indication of that. Copper should be brown, not pink or orange.)
Thanks, on the wear area along lapel and in a ding spot in front of the date it shows a silver or zinc color.
Looks like some heavy wear, at least on the obverse. If the reverse is at least as worn (or more) it could account for the light weight. Steve
Recheck your scale. A silver dime planchet would weigh 2.5 grams if this is a cent struck on a dime planchet and having picked up a copper coating. I would put it on my machine that would identify if it is silver or copper. I have an AU 1943-s and F 1928 cent on silver dime planchet but neither struck up with complete upset edges like your coin. Have the coin non-destructive tested to determine metal content. Like one poster mentioned it could be on a rolled thin copper planchet. Happy error coin collecting.
It would be greatly appreciated if you would post the results when you get it back from NGC. (Especially if it's struck on a wrong planchet).
