Hello everyone, I'm new at this and trying to learn a bit more. Recently I found several coins that caught my eye. They seem to have a second image. Is this what is I've heard referred to as a double hit? Is it worth keeping? In the first picture, it is a 1990 D penny and the last 2 numbers have what look like a double image. The next 2 pictures is of a 1992 D penny that has what looks like double images on the date, mint mark, and an extra image all around Lincoln's head. Some of the letters in "In God We Trust" appear to be flattened a bit. Thank you in advance for your help.
Hello all, Right after I posted this, I saw a post above it called [h=1]Learn About Die Doubling...[/h] so I read it and tried to click on the information sites. The first 3 did not work and said 404 Not Found. The 4th one took me to an excellent page called Ken Potter's Educational Series. I only got a brief look at it before I decided to post an apology here as I should have checked his page before I posted my questions. But I didn't see it until after I'd posted and was taken to the forum page. I'll be reading up on it more. Thank you
There's no apology necessary. It appears that you have an example of machine doubling, which means the planchet failed to eject after the first strike, and was struck again. Machine doubling is characterized by flat shelf-like impressions around the main devices. On your coin you can see it around Lincoln's portrait as well. It could also be an example of die deterioration, but it's difficult to say from the angle of your pics.
Your description of how machine doubling occurs is incorrect. What you are referring to would be known as a double struck coin. Machine doubling occurs as the coin is struck. As the die descends on the coin leaving the first strike, it bounces up ever so slightly and lands down lightly enough to flatten part of the design, but not strongly enough to leave a second strike. The coin pictured in this thread appears to have push-plating doubling and offset die wear. Here is a tutorial thread I have done on different types of doubling. http://www.cointalk.com/t224087/ Keep up the hunt!
No need for an apology TS, if you have questions just ask. We are all here to learn. You can also search the old threads and find lots of great info there too.
Thank you John Anthony and non_cents. I appreciate all help and this was good. I too, until now, thought that a double die was a double hit. I read non_cent's post on Let's talk doubling and learned much. Thank you very much for that. I've found some other pennies I have questions about which I'll be posting shortly. I've also found in the coin rolls, 10 Canadian pennies, 7 dimes (paid for 1 1/2 rolls of pennies!), 1 korean coin smaller than a penny, 1-2 Euro coin about the size of a penny, and 2 of those flat 2016 batteries. Batteries! I'm sure others have found some strange things in their rolls (especially the larger coins), but for me this was strange and amusing. I showed them to my teller and she said the bank would like it to investigate, but I told her I'd rather keep them as part of my coin collecting experience. Thank you both again. Good hunting!
