1989-P LMC DDO New Listing

I dunno. I think I see light separation lines on the date and stronger ones on LIBERTY, but these faint separation lines seem to be common on many cents between 85 and 89, so I wouldn't necessarily attribute that as DD. I definitely don't see any notching.

This is a class 6 doubled die - I can tell because the digits of the date are thicker toward the rim than they should be. No form of Machine Doubling makes letter thicker than they should be. On class 6 doubled dies there is commonly no form of notching or separation lines, which distinguishes class 6 doubled dies from the other classes.

This is as much of the date that I can get in one pic using a microscope at x60. The first pic is the DD and the second one is a regular at the same magnification, it might help in comparing the two

1989 seemed very popular for obverse doubled dies with a Class VI doubling. I have somewhere around 15 or so different dies, all fairly minor in the collection that I have.

They are grooves. Some variety folks call them separation lines but it is better in my opinion to call them grooves when the spread is this close.

Separation occurs when the details are spread in such away as to actually have a separation between the images.

Their may be debate on this but this is where I fall on the definitions.

Also, these pictures make it clear that this is, as Chuck called it, a Class VI DDO.

I don't remember anymore if it was John Wexler or Ken Potter who told me at least ten years ago that there were 29 or so, known 1989 DDOs at that point. It's probably more by now.

You will see grooves on earlier strikes of Class VI doubled dies. As the die wears the evidence of doubling looks more like wider letters and numerals.

That is not to say that wider letters and numerals makes every coin that appears that way a doubled die.

Excellent point coop!
