Closest I can figure on this is a die gouge? The line seems to go through the memorial but is not shown on top of the memorial itself. Or is this some sort of bubble since it's a zinc penny? Thanks for any opinions! btw, sorry for the weird coloring. I'm having difficulties getting this usb microscope to behave on Linux.
Interesting. Since the issue is on a Copper Plated Zinc Planchet I'm leaning toward a Linear Plating Bubble.
It does look like a blister. But it is out of alignment with all the other linear plating lines. While it is interesting, I don't think there is a feasible way to to made a positive identification, unless you could find another one just like it...
No such luck so far I went through my whole jar ($34 in pennies) before I started posting these pics. I think you guys are right - with the other blisters I've seen on pennies in there, I think this is one too.
Wow, that looks like an extreme version of the plating blisters I saw on this coin: https://www.cointalk.com/threads/orange-peel.379842/ It's called a fold?
Thanks! I'm definitely appreciating all the help people are providing in here. I'm new to coin collecting, but I'm pretty sure I'm hooked.
I was sure I had seen this same coin on an earlier post, but now I am unable to find it. Anyone else think they saw a similar coin?
Here's some better coloring of the coin if it helps any. Think I've got the microscope figured out...
Interestingly, one thing I didn't notice on there until I started blocking some light is that the bottom bubbles are in a V shape.
Looking closely at they 'v' The left side looks raised, as in it's a linear plating bubble. The right part looks incuse, as in its taken a hit and metal was gouged out. SO coincidence, but that's my take on it.
sometimes gases in the metal planchets expand and cause weird "bubbles and deformities" when they are heated accidently or on purpose post mint.
