I am assuming that the raised area on the reverse that spears the first "S" in STATES is a minor strike through error. Is there any premium associated with this type of error? And if it is not a strike through, what is it? Thanks for your help.
In most cases it is called a die gouge. A struck-thru coin will have a indent on the surface. Look at the post that is one head of yours posted by John65999. http://www.error-ref.com/die-gouges/
A strikethrough would've obliterated the S, I think. The fact that this feature goes under it is interesting. I will defer to @alurid and subsequent future respondents to the thread on what to call it, since errors and varieties are not my field. Neat thing, though.
I can see 4 parallel marks, E, D, S and the second T. Could be a planchet issue that wasn't struck out, or possible feeder finger gouges on the die, although I do not know at what position the feeder fingers are placed
Looks like the die was damaged and it was transferred to the coin during the minting process. In other words, a nice die gouge.
