Not just a grease filled device. this area was notorious for "fixing" die clashes by over-polishing down to barely no depth left. This also had a tendency along with die flow and movement to stretch and widen the details. It would then be real easy to ruboff the die face and leave residue in the small cavity  Edited by Crazyb0

 Maybe a combination of a filled die and over-polishing. In Memory of Crazyb0 12-26-1951 to 7-27-2020

Considering wear, corrosion and a filled die perhaps, the remnants of the FG can be easily seen,with a particular lighting a lot of details can disappear.I enhanced the pic a bit and FG is more noticeable, that means it is not considered no FG.  |

I do not see a grease issue here,but I do see an over abraded die and still visible FG.Value=1 cent. John1  |

The difference between the two?Grease partial fill will make the devices look wider:  An over polished die will make the devices shorter in height and appear smaller on the coin.

Richard, please correct if I'm wrong about this. I have always thought that on a VLDS the details widen due to the stretching action of metal flow. At this state of die life, it has been polished, i.e. repaired numerous times both decreasing the depth of device and causing the possibility of a Grease Fill. Add the movement of flow, then how can one difinitively tell(w/o a micrometer) the width increase relating to each? It would seem that factors such as bust sizes and device distance to rim may give some clue. I know there is a difference between the two, at least in thought, but how is it determined in the practical? In determining what is a fill or a polish? |

When an area is reduced by die polishing, the devices get smaller:  Note how the devices near the rim are now smaller in size. (this is a proof die that is used only for 6,000 total strikes) But note how the reduction affects these devices. So if the 'FG' was polished out, then the tops of the devices would be showing as reduced in size. (thinner than normal) On a grease filled example that was not fully filled the die would fill in the smaller areas first, then eventually full filled areas. This could happen as once also if there were a lot of grease in that area) But to me what I can see on this coin looks like the tops of the devices with the lower part polished out. Thus I reasoned the die was polished so much that only a small portion of the 'FG' now shows the deepest part of these initials. Thus the 'FG' is smaller in size. The grease filled examples would show a wider 'FG' because the lower part of those devices would be filled and the wider lower part of these devices would be showing.  Notice the non filled devices how narrow they are and then the grease filled devices. How much wider they are? I've been looking at the 1969 missing initials and the listings from PCGS show two different dies, but both are considered the same die number 901. So they probably realized that this was happening on more dies and quit slabbing them. http://www.PCGScoinfacts.com/CoinIm....aspx?s=29171969-D. |
