1961-D LMC 1961-D-1MM-048 What Do You Think?

The biggest problem with that number is that the RPM does not have a tilted with the split serifs. So I would say no for a match for that one. Still looking to see if its is listed or not though. yours is a RPM, just not this one.

There are several different types of RPMs. Here is a list of what there are:

Note the last 4 on the bottom row. A tilted occurs when the punch is not vertical when it is struck. The location might be close, but was not right on top of the previous punches.
Here are some examples:

Note the ones with 'T' on the lower corners. That denotes that the serif/serifs have split/splits on them. Here is an example from the same year:

Note the splits on the corners of the mint mark? Those are called split serifs. They can denote a tilted, but other events will also cause split serif.

Well looking over the listings, I didn't find a match. There was one that was close, but the split on the serif was slightly different and I determined it wasn't that die. I wanted to show you so all could lean a bit more on die attributions.

Note the location of the upper split. That was the thing that disqualified this one. I didn't even make an overlay for the locations. The split in the wrong place told me it was not that die.

That what I do. Always the teacher. I make images for questions not even asked yet. Just getting prepared before they are asked.

I was just looking at Coop's example again. I notice that it compares my RPM to 083. I was comparing to 048 - especially because of the protrusion out of the mint mark on the upper right portion. I have looked at coppercoins, Wexler and CONECA and, unfortunately, none of their photos are clear enough to show split serifs. Wexler and CONECA do, however, show flow lines around the mint mark which are, at least, very close to mine, if not identical. Wexler shows those flow lines most clearly and distinctly.

The problem, of course, is that I am unable to find any of the other indicated markers. I am able to take Wexler's image and enhance it a bit to where there is a semblance of a split on the upper serif. It appears to be in the same position as the one on my coin but that is not conclusively clear.

Bottom line is that I am not yet convinced that my coin is not a match with 048.

I have taken another photo of the flow lines on my coin and enhanced them by sharpening the image. This photo is for comparison to Wexler's image 048 here http://doubleddie.com/311222.html

That little protrusion is pretty distictive (on 048). It shows better on your earlier photos but gets pixelated away on the last one.

What is the overall condition of your coin? Is it circulated or fresh?

The split serifs is the biggest concern. It shouldn't have them for that die number.

Thanks Doug

Can you give me a link to an 048 where the split serifs are visible?
