There is a big spot that is missing what seems a layer of metal. The whole area was clad with copper. the scan shows the area but its not rust, just high contrast and brightness to show the detail of the area. I have also included a normal photo to show coin finish. Is this common with new coins? Was it a damaged planchet?... Scan

I would agree -biggfredd- Looks like strukethrough grease!
---t/c guy- this is not odd, it is common to many dates and denominations!
---I might say I've seen this more in resent years though! Worth Face $.01!

The more recent ones have this defect where it looks like the surface is missing pieces. Struck through or damaged planchet. Here's a struck through grease/debris from a 1964 cent:  |

When a coin is struck normally, all of the original marks on the planchet are obliterated by the strike(planchets tend to be pretty scruffy). When a coin is struck though grease, the planchet marks are preserved on the area in question which is why it always looks so much rougher than the rest of the coin.

OK, I understand Struck Through Grease, but this does not have the through grease look. its like someone actually cutout one layer of metal before the coin was clad with copper. It is actually a 'valley' or 'pocket' with a physical 'ridge'. So I am guessing planchet damage...? |

Give us an edge on angled view if it's actually got a depression in the coin surface. Pics are only 2D.
In theory it could be missing a little plate there or something, but in the 2D's we have at the moment is does look struck through.

"Grease" is a generic term for press gunk. There is a lubricant aspect to it but the grease also binds metal dust and hardens considerably. This hardened gunk can create that type of depression on the coin. Larger buildups will clog devices and if the gunk falls out and is subsequently struck into the coin, the result is a dropped letter error- a perfect incuse impression of a device letter.

"Struck through debris" will leave ridges like this. For example, struck through a bit of metal that has flaked off of another planchet.

Thank folks. Struck through it is. I just found another one a 2009 cent with the same type ridge with the 'T' and 'H' just done in. Classic STG. Thanks for all your input!   |
