Impurities in the planchet have caused the lamination error and it looks like two separate die chips in the ear.

Thank you for your service Bill and happy Coast Guard Day!

I have to agree with coinguy. Original coin is 1941, impression coin is 1943.

Nice find.

The “W” means it was made at the Winnipeg mint.
Value is most likely $3.

Agree with coinguy, looks like damage from an electric engraver or some other device.

An acetone bath should show you if you have a dirty coin or a foreign planchet.

What is the weight to 2 decimal points?

Welcome to the forum, you can use the banknote and other sections on this site to find values.

It’s a fantastic bill if authentic, listen to the dealer and get it certified.

They will grade it, plus it lets you show buyers that it’s the real deal, which grows your potential audience and that will command a higher premium.

Not enjoying that Felix is more organized than me.

Unlikely that happened during printing, even if it did, I doubt it would add any value, probably detract because it’s not very appealing to look at.

The low serial number adds value, but the ink mark someone added detracts from it. Search EBay for like bills to get an idea of value.

Not an error, just someone with extra time and a pencil.

Raised metal like that usually means a die crack or a retained strike through.
