Hello , I bought this straight graded Pcgs 8 reales and it appears to have a strike thru on it? Obverse and reverse. Is it a variety unlisted or ?? I would rather not guess myself 😀@TwoKopeiki. Or anyone what are your thoughts.
? Thanks

Missing metal (silver) is what I see. I do not see chopmarks of any kind. On the pillar I am not sure but again could be pressed down metal with some kind of tool.
Thanks for the response, but I don’t think Pcgs would straight grade the coin with what you are describing. ???
Looks like a pen is on it...

I do not believe they would either.
Something created those lines / tool marks on the planchet. Must have been pretty deep to not be obliterated by the striking.

Thank you, !! At least now I have an explanation. Pcgs obviously believed something similar or it would not have straight graded..
You are the resident expert!😀
Zooming out and looking at how it presents on the neck to a less severe extent, I was thinking those are just really bad planchet flaws

Given the linear nature of the flaw it was probably from one of the passes through the roller mill that turns the silver alloy ingot into a strip with the proper thickness. IIRC Swamperbob mentioned a step in the process to prepare the strip for stamping the blanks that involves cleaning and removing lamination issues from the strips. Also, improper annealing can lead to the planchet being struck without the necessary malleability to press out any remaining planchet flaws.
Here's a link to swamperbob's description of the lamination process
Thank you very complete and informative replies.
I’m frankly a little confused by this coin.
Look at the reverse and enlarge the image. The flaw is on top of the viewers left pillar and part of the shield and then under the castle’s foot.
Hummmmmm………
