Hello and Welcome,
A couple of thoughts....
I am not going to offer a grade on this coin as I am terrible at grading and you seem pretty proud of this one so I do not want to offer an opinion that may not be accurate....
For this date and mint there really is only one VAM
series that holds any kind of a premium and that is VAM
2.. (2,2A, and 2B) your coin is not one of these... the differences between the other VAMs are very subtle and probably would require microscope photography to positively confirm the exact VAM
All that said the good thing is there are not a huge number of choices for this date, so by looking at the date position on your coin (and ruling out the VAM
2 discussed above) your left with normal position VAMs 1,4,5,7,8,9 and possibly slanted date VAM
I would suggest going to the link below... Get out your magnifier, and see if you can nail down exactly which one it is.http://www.vamworld.com/1891-P%20Obverses
I hope this helps and sorry I could not exactly identify what VAM
your coin is from the pics.(maybe someone else can?) .. like I said the variances for this date are VERY subtle.
Good luck!! Let us know what you find.
