2020 s Silver Eagle Strike Through question 0

[Crigg]

Hi,

Im just getting into to collecting and opened the Proofs that I ordered from the mint and discovered that a couple of them had the same mark on the reserve - on the shield.

To me it looks like it is a small strike though, but am looking to get a few recommendations from people that are more knowledgeable than myself, before I spend the money to get it graded and pay the extra for a error only to have it come back as not a error.

 

Not knowing much about the striking process I am guessing that there is a dowel or something that pushes the struck coin off the die - could this this be a mark where the extra polished wore off or does it appear to be an actual strike though. Another reason I am some what leery is that 4 out of 6 of my coins have a very similar mark in the same spot. 

 

Thanks,

Corey

It's too minor to be noted as a mint error by NGC.
