Estate40 Posted September 5, 2020 Share Posted September 5, 2020 (edited) It looks like something is wrong with this 1961 D penny. Is it build up of material when it was struck? Is that why the D is filled in? Or was it struck multiple times? I'm confused. Please help to clarify thank you. Edited September 6, 2020 by Estate40 So I took the penny out the folder thing and added the pic of the back side. Link to comment Share on other sites More sharing options...
Coinbuf Posted September 6, 2020 Share Posted September 6, 2020 Welcome to the boards, just to clarify coins are not stamped but struck, and yes it is possible to have double and triple struck elements. However there are no known examples of any double die coins that I know of for this date/mm. I think you have a coin that is exhibiting what is known as mechanical doubling which can be either strike doubling (caused by the dies bouncing at impact) or die deterioration doubling which occurs from over use of the dies. However the coin is very well worn so its impossible for me to be sure which. Mechanical doubling is very common and can be found for almost every coin and every year.

Just Bob Posted September 6, 2020 Share Posted September 6, 2020 (edited) Welcome to the forum. I am going to agree with Coinbuf. Extreme die wear combined with extreme wear of the coin. Edit: Apparently I am wrong. Read the next post. Edited September 6, 2020 by Just Bob Estate40 1 Link to comment Share on other sites More sharing options...
Member: Seasoned Veteran DWLange Posted September 6, 2020 Member: Seasoned Veteran Share Posted September 6, 2020 That effect is not the effect of die erosion or circulating wear. It has been subjected to some abnormal abrasive action, such as being run through a rock tumbler. Normal wear looks nothing like that. Link to comment Share on other sites More sharing options...

If it was in a Tumblr I believe the other side would be all messed up. I don't know how to take a really good pic thru the microscope with my phone.

Greenstang Posted September 7, 2020 Share Posted September 7, 2020 This is why you should always show both sides of the coin when posting. If not a rock tumbler, then some sort of other damage. It is impossible for what you see to have occurred during the striking of the coin. As far as the mm goes, it may be a broken post. A common occurrence with P & D mint marks.

James_OldeTowne Posted September 8, 2020 Share Posted September 8, 2020 My first thought was: that coin spent A LOT of time at a laundromat - ! Estate40 1 Link to comment Share on other sites More sharing options...
