Just going by what looked like that coin's issue in error-ref. Noted the pics that showed similar fractures (The 2002 Brazilian 10 centavos)
Paddyman, could it be a deep lamination error? Thanks in advance. Welcome to CT Claireishere, and good luck with your father's collection.
I believe there's no doubt this is glue. I don't think the OP has soaked it in acetone. Distilled water isn't gonna desolve glue.
This looks like it was caused by Die Subsidence (Sunken Die) in two areas of the Obverse. See this Link from ERROR-REF.com for a description of this phenomena: http://www.error-ref.com/die-subsidence/
lol, i always get side tracked when i go to the error definition page, and i love it, it turns a 2 minute read into a half day instruction in errors, i love errors!!
If dipped in acetone, would settle the the glue question. Unless left in distilled water overnight, any kind of glue that's cured for decades would just sit there and raspberry you.
Comments like this make it difficult for those starting out to learn. At no point did I say it’s an error. I just asked what it was.
Sorry to harsh your mellow Welcome to our world So many things show up here on the Error Forum that aren’t worth what people think, I may have been short with you You did get some responses from some much more knowledgeable than I am. Such as @Fred Weinberg , @paddyman98 , @Oldhoopster , @Kentucky I’ll try to be a better person
It's not a mint issue of any kind (notice I didn't say error) it's PMD In my honest opinion which I have already given.
@Duban coffee Mr. Coffee.. Is there something you would like to share? If you're going to quote me then say something.
