Occluded gas bubbles under scope

Just revisiting an error coin with close ups from my microscope. Someday, this one will get certified and placed into a certified error-by-type collection.

Nice!

Here is one from my collection

 

Also nice! What do you think mine might be worth? It's certainly not for sale, but I want to keep better track of my coin values for submissions and for later in life. I'm thinking ~$100?

 

Nice coin @Seattlite86. I haven't often seen older cents with this error. Is it considered a planchet error?

 

I think the short answer is yes, since the gas bubble has to start in the planchet and expand when struck. I've only personally seen two, and the other one only because of @paddyman98

That's a very strange one. What a brilliant example of it.

 

That's a cool error! I dunno why, but I love planchet problems.
