What kind of error is this?

And is it worth having slabbed?

Looks like glue

Give it an acetone soak and it will be back to normal.

I don't think its glue. You can't see in the pic but the backwards United under the date is doubled

It’s glue – or some similar substances – it’s not an air of any type I’m sorry to say

I know pretty much nothing about errors but as soon as I looked at it I immediately thought glue.... So it's actually not an error which why I knew something about it... LOL..

Okay, I will try that and see what happens. I didn't know glue was part of the process or if an after problem that could resemble copper. But, I am a newbie

Okay I soaked it a few times in acetone and now I can see where the rubber meets the road. Most of it is still there but now its obviously applied...Thanks!!!
