I was wondering if anything stuck to the surface of a coin, not suppose to be there, is concidered an error. I have a few coins that have small blobs on them. Also, what about depressions in the coin. I regularly see coins with very small depressions in them. Looking close in the 10-20x loop you can tell the where not from bag bumps or circulation blemishes. I worked as a die maker for some years and can usually tell when something is from stamping.
Are these very small and almost unnoticable errors of any real value?

ODD, a lot depends on where these blobs are. They could be just die chips that fill with metal when the coin is pressed. First thing your going to learn here is everyone loves pictures, pictures, and more pictures. They really help to evaluate your coin. And welcome to the Forum...

Hi OrDirtDevil
It all depends ,, some struck throughs have a premium while others dont,, the ones that carry the best value are those where the object is retained in the coin,,such as a piece of string, or wire, or other foreign particles ,, those that leave an Identifiable impression would in my mind come next and then those which are indistinct like grease oil and other substances which cause weak or distorted areas on the coin.
I however keep all such coins not so much for monitary value but because they are different ,, and interesting.

Thanks for the replies, this place is full of information and help from you people. Can't believe the responses and help already shown here. Image:  1986blobfinal.jpg75.17 KBHere is one fo the coins I am referring to. Its a 1986 with a speck by the forehead. It look to be of copper material and seems to be fused into the coin. Picture might not be the greatest as I am learning a new camera, but should be of some help. It will atleast give you some kind of idea what my question was about. Hope its hood enough. |

A picture is worth a thousand words. That would be an odd place for a die chip to occur. Could be a piece of scrape fell onto the planchet and fused into the coin. As for value, maybe one of the error collectors will come along and help with that.

That looks like a piece of the copper plate that has folded back from the corrosion eruption (the hole) in front of it, this is fairly common on the copper plated zinc cents.

Way to go Rick. I would have never noticed that hole. Just a dark spot on the coin to me. Good thing mine weren't the only eyes looking.

Here are the Pics I promised The center cent is probably the one which can be used to check yours,, notice the surface of the coin has little bumps all over it ,,these are gas and or corrosion bubbles caused by corrosion underneath the plating, eventually they will erupt the surface and look similar albeit a bit smaller than the ones on either side of it,,  Closer  Metalman Edited by Metalman
