American Samoa Quarter with interesting grade from ICG sub

I figured this one could be its own thread. Part of my recent ICG sub had a colorful American Samoa Proof Quarter. ICG gave it a PR 69+ grade (the plus with a 69 being less common and not done by PCGS or NGC; I don't think Anacs does it either).

Here is the raw photo and then the slab:

One of mine came back with that grade also.

 

Gases inside the proof holder to create the toning?

 

I'm confused; I thought RAW meant outside of the slab?

 

I think what Michael was wondering is did the toning occur in the proof packaging. Or was it sold as a raw coin in a flip?

 

Very nice!

 

I think there are several potential explanations for the toning:
1) The original proof set was stored in a hot/humid environment for several years
2) Someone accelerated the toning with heat or chemicals
3) It was left out in a favorable environment that caused the toning quicker than normal (but no chemicals were applied)

I bought it raw from a seller on eBay about two years ago. I bought an Arizona state quarter from him as well that had rainbow color. That one I resold raw and the buyer received a straight grade from PCGS. So while the color might be questionable, some of the grading services are calling it market acceptable.

 

By raw, I meant not in a grading company slab. The first picture was taken inside of a generic self-slab where I was storing it before sending to ICG.

 

I bought it on eBay raw in a 2 x 2 holder (not in the proof packaging). I then kept it in a generic slab (lighthouse) before sending to ICG.
