First I'll apologize for the rough picture. I'm not a photographer. The dash in the words, "In God We Trust" has a raised bump that appears as a dash in the word, "We" of the obverse side. I've had the raised bump tested and it's a solid mass with no air pockets nor trash beneath the laminated copper plating. It comes up as solid as the rest of the coin. My best guess is that this is a dented or chipped die. This can be seen without the aid of a magnifying glass so I'm also guessing this to be a major variety. I'm open to all opinions of, "What's it worth?". Thanks to all in advance.
It's a plating blister. It's a very common occurrence. Push on it with a toothpick, it'll collapse, proving my answer. Sorry, but it's only worth one cent.
its a blister, not all blisters will collapse, plating blisters are hollow, Solid blisters are pushed up by gas under the expanding metal caused by contaminants in the zinc (zinc rot)..
I agree with the others Plating Blister - I want to share this webpage with you http://www.error-ref.com/blisteredplating/ Your Cent has a common minor error. Thanks for showing us.
The raised bump was tested using an Eddy Current Machine with an open probe. It tested solid with no imperfections. It's as solid as the rest of the coin. My question was, "What's it worth?" I'm already aware of what variety type this is.
A Dynamometer? Eddy-current testing uses electromagnetic induction to detect flaws in conductive materials. There are several limitations, among them: only conductive materials can be tested, the surface of the material must be accessible, the finish of the material may cause bad readings, the depth of penetration into the material is limited by the materials' conductivity, and flaws that lie parallel to the probe may be undetectable. This is a Zinc coated Cent. Might have received a bad reading. If it is solid it's really not a major find. It's not a clash. I don't think it's a Die Break or Chip. Maybe a slight Planchet Flaw. Can't put a value on something so minor.
The OP is convinced that he's right and the rest of the world is wrong. There'll be no convincing him that he doesn't have something that will allow him to retire rich.
That comment was uncalled for. This isn't a forum to harass, demean or belittle other members. I'll ask you to kindly keep these such comments out of the discussion.
An RD 1993-D will get you $12 on the PCGS Price Guide if you pay the submission fee and get it into PCGS plastic at MS66. The plating bubble is a common defect, and would probably even lower that value. It's a plating bubble, and they come in all shapes and sizes.
Possibly worth a ton of money, take it to a coin shop (or more than one) and have the people there examine it and evaluate the value, if you don't trust people on this forum. Let us know how it turns out.
I've always been told that gas bubble like this indicated counterfeiting? Is this just on some coins or metals?
