I found this 1966P penny while roll hunting. The reverse looks like it has a slight Doubled Die? I was wondering if someone could help or verify if this is a DDR?I will try and get some better close ups with my cell phone on the reverse. Looks like most of the letters on the reverse have a slight Doubled Die.
I am looking at the letters of America in the picture I posted and most of them have a slight extra stamping(?) to the right of each letter. This is on most of the other letters on the reverse that I have not posted pictures of. Not sure what has caused this?
Like Frank aka @Treashunt said, it is machine doubling. There is a difference between true hub doubling and machine doubling. Hub doubling transfers a doubled image to the working die, but machine doubling is caused by the vibration of a loose working die in the course of producing a coin. Chris
I guess I need to be able to tell the difference between the two. Do you know of any web sites that might teach how to tell them apart?
Here's everything caused from machine doubling .. and make sure to click on the links on the page too . http://www.error-ref.com/machine-doubling/
And, every copy of the CherryPicker's Guide to Die Varieties has a section in the Appendix discussing, and showing, the different types of doubling, from doubled dies to mechanical doubling. A good book, and highly recommended to lots of folks here.
I see a normal coin way to close up. I also see the tapered sides of the block shaped letters those can look like doubled images. Put that with the wrong lighting and the tiny smoke and mirrors can trick us all!
I love that illustration it shows the results of MD perfectly, it’s just how it looks. Thanks for digging that one up.
