I found an interesting coin in a bank box stamped Jul 2004. The entire box was 2001-D Kennedy halves, and all the coins were very shiny (one graded MS65 by PGCS). The coin is pictured in attachments. Any ideas as to what type of mint error this might be (die adjustment error, struck through grease, etc.)? Some of you more experienced collectors may be familiar with this. It is struck the same way on the reverse.
That is cool. Did you go through all 1000 coins? If you did, I give you credit because I would've dumped the entire box.
2001-D "ring" error I haven't actually measured it. I will measure it tonight. As soon as I found it, I put it in a 2" by 2" holder.
Yes, it looks like the same size as other Kennedy halves. If it is a struck through grease, why is it stuck identically on the back? It doesn't seem likely that there would be grease on both the front and the back of the coin, with the same "ring" pattern.
It needs to be weighed to be sure it was struck on a properly prepared planchet. If the weight is correct than the coin was very likely struck through a very heavy layer of grease. The coin is not worn nor was it struck by a worn die. Let us know, if possible what the weight is. Thanks, Bill
Where can I find a good scale that I can use to weigh it? I have a postal scale, but that is not accurate to the gram (only to ounces).
If grease gets between the dies it is definitely possible and more often then not likely that it is on both sides.
Having a knowledge of spiking Mathias. I believe it can me cased by a number of things at the same time. It would have been nice to see the photo from the other angle looking down from the head and seeing the other side. Basic The Die has collected clad inside the outer edge of. The first thing I would do is check the weight. See if it thin/light. The die is probably a little warped. This would help the clad gather in the outer area of a worn die. It could be....
