Ooo ya it came with some really tiny disc, I'm not sure but I assume the program for the scope is on it, I'm not sure my laptop has a thing for tiny discs, it's like 3×3 inch disc or something

@coop, I was just thinking about what you said about the grease filled devices, even after the die was wiped and grease pushed to one side of the device, in that situation wouldn't the grease still not fully get rid of part of the device? With the amount of pressure in a strike wouldn't the grease get spread out once the strike happened? It seems weird that grease would only narrow the devices but not effect them in any other way, though this does seem to be the only possibility. I'm picturing a Grease Filled Die on these devices, wouldn't the grease still effect the area around the device? I imagine grease would not completely just slim the devices and not effect them fully, or at least iv never seen an example posted. Have you ever seen this sort of thing before? I only ask because it's really noticable but I can't find info in the topic. |

If possible @coop could you add an overlay image for the coin? If the devices are narrowed due to Grease Fill the back of the 9 should be in the correct place and ony the front was narrowed or vice versa. But if it's grease on one side both sides of the 9 and 7 should not be effected correct? |

The die may have had some Feeder Finger Damage?  Overlays:    Or the normal polishing would also affect that area of the die reducing all the digits? |

@coop, overlay was the wrong request, I don't think there is Feeder Finger Damage, I meant is it possible to take my image of where the devices are reduces on overlay the same coin but how it should look. Though thinking about it now that's kind of a lot to ask:p the devices just look so smooth and precise, this could be a semi common thing maybe I just have yet to see a cent with smaller(or larger) devices that was not either MD DD or DDD. So this really jumped out to me. A partially Grease Fill on the devices I wouldn't imagine the result to look like this. That's kind of why I questioned font. I also still don't know what going on with what appears to be a little bit if extra metal under the curve of the first 9. But I'm nothing if an expert compared to someone like you coop, or many others on here. Compared to you all I'm just a child numismatic:p |

The purpose of the overlays is to show die clashes, but also shows the opposite sides of the coin for coin damage pressing through the opposite side of the coin. Also if a polishing took place, how it might affect the devices. Seeing then on one area helps us see the full picture.

I agree with JimmyD about MD.
The shadowing of the left of the legs of the 97 is what I'm seeing as MD.
Without a whole coin shot, it's difficult to tell the die state.
(Overpolishing is a possibility to remove damage or maintain the dies, but at some point, the mint seems to have given up on polishing dies and just changed them out. It's probably more cost-effective with today's production techniques.)
EDIT: I'm seeing what appears to be radial die flow lines coming off the tail of the 7 towards the rim so I don't think it's been overpolished.
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.

On the last image, all the obverse devices look thinned from a die polishing.

@coop, I assume that just because it's a natural light cellphone picture. But we already know the second 9 and 7 in the date at thinner then they should be but the 2 and 9 look normal, should I post other imagest of the coins devices?

Looking now at reverse image, it's showing the same as the obverse. Just reduced devices because of field reduction. Not a premium for the coin.
