Hey all, was just flicking through my collection and took a closer look at my Abra, the stamp seems significantly more faded than my other 1st ed stamps.
I was wondering if this is a ‘grey stamp’ I occasionally hear of? I have put a reference photo.
Thanks in advance 
Not sure if the photos attached correctly - anyway, here are some gyazo links.

will need more clear photos in better lighting
It could be, need better photo to know for sure.
Heres some more from a few different angles.

Looks like a full black stamp to me.
But cannot say due to lack of contrast due improper lighting. Open up the windows, turn off your yellow lamps and shoot a photo straight from the front.
here example of my abra grey stampcheck if it similar to mine.
