Suddenly I'm finding RPM's in a couple of mint sets. They aren't giant splits and I would feel better with a second opinion. Thanks.   |

Die Deterioration I feel--die state at end of life--must happen to thousands of coins--miss-management at the mint?

If all the coins has the same split on the lower serif, it sounds like a bad punch issue?

lambecolin: How does Die Deterioration produce split serifs on both ends of the "D" and nowhere else on the coin? coop: If the MM is punched onto the hub or die then wouldn't every coin's doubling look identical? Edited by whatsthedillio

Hubs are used to create dies. Dies are created to make coins. Mint marks are added to the dies (Pre 1990 by hand) to the dies to show from mint the coins were struck. Here is the progression:  The same punch is used on all denominations from a mint until it is retired. So if all you coins have the same splits, they may have been caused by the punch and not from re-punching? |

Thanks for the diagram, I like knowing that type of things. Yes, the punch may have been broken with the operatives word being "may have". I'm still new at identifying broken punch but the ones I've seen that were labeled as such had a different look then the split serif when examined closely. Broken punches seem to have a conical shape where the top part comes to a point. One of the 1973's I posted I drew arrows showing a broken part next to a serif shape. The doubling I'm seeing here doesn't come to a vertical point but gently curves over the top of the letter. As I'm beginning to research this a little more I see that there are different grades for the doubling part (see also the link I provided where an example of class VI doubling). I'm getting the feeling that there is push back on any doubling that isn't spectacular. Why have different grades if only the top grade is acceptable? But it doesn't look at all like die deteriation to me because that looks more like smooshing of the metal. These MM are pretty crisp. http://www.errorvariety.com/OFD/DDD.html |

1. Grades are based on 1-59 for circulation coins. MS-60-70 are mint state grades for condition of a coin.
2. Die states vary from the fresh dies-EDS-MDS-LDS-VLDS and in between. These denote the state of die wear. Some varieties are affected by die wear. The outer doubling on a doubled die may be concealed toward the rim, but the inner devices may still show the doubling. On RPMs the shape of the mint mark changes some with age. So RPMs may get weaker with die wear (When it is on the mint mark) and some times they get stronger when they are in the field areas.
3.Then there are die classes that identify the problem of how the doubled die was created during the hubbing process.
These are different aspects of a coin.
Normal coins will be graded by the first note in the thread.
Varieties are graded with the parts 2 & 3 of this thread.
I think this is what is confusing you. If not, ask another question.

I think this is what is confusing you. If not, ask another question. My topic is really about this coin which I believe to be an RPM. The pushback I'm referring to is the example provided to convince me that it's not in fact a proper RPM. The example was what I would consider the most extreme example of RPM available. Just a quick search in my browser came up with a different example of an RPM that claims to be a CONECA listing. http://www.briansvarietycoins.com/shop/view/3989If that is an RPM, then I feel pretty sure the one I posted here is also. |
