ANACS (Possibly) Under Graded Coins

Grading is subjective. I've sent off coins that came back a lower grade and I've purchased coins that I felt were overgraded. It happens.

Agree. The V-nickel looks possibly cleaned in these pics.

AU55 on the V-nickel and VF35 on the rupee

Although we may be able to look at on screen pictures and perhaps give an opinion based on what we see,
A third party grader has five advantages that we don't:-
1. examining under 10X magnification
2. ideal lighting conditions,
3. raw, hand held,
4. extensive comparative experience over hundreds of coins of the same type and
5. not under plastic.

For these reasons, I will always favor the declared slab grade, despite the fact that they sometimes get it slightly wrong.

If you are not happy with the slab grade you have to either
a). swallow your pride and still accept, or
b). pay the extra fees for re submission.

For various reasons, none of my coins are slabbed.

,only way for us to answer your question .

I say AU-55 on the nickel
And XF-40 on the Rupee

I couldn't find a graded example of the Burmese 1/4 Pe for comparison, but PCGS seems to be all over the map on sub-AU grades for the silver types of this era with similar design.
Look at the XF details coin in the first link with far worse detail than your coin, followed by the VF details in the second.

If the grader felt it was a weak strike rather than wear, maybe you get into an XF?

I'm not a fan of slabbed coins in my collection, so if these were mine and I didn't like the grade, I might just remove them from the slabs. But if your goal is to have the best grade you can get from a TPG, sounds like you have good consensus here on what you might get with re-submitting.

Patience is a virtue ...

@navycapt, after checking eBay on that 1/4 Pe, yeah, seems it should merit XF pretty handily.
Whether it's worth it or not is a different question.
