What is the highest grade assigned to a 1969P quarter and can you post pictures of high grade exampl

I recently picked up a 1969 Mint Set with a clipped planchet 1969D 40% silver half.
I took a good look at the 1969P quarter in the set and decided to cut it out of the cello. I am very surprised at the high quality of the coin. Usually MS 1969P quarters are ugly, with excessively flawed planchets. The one I cut out of the mint set has very few planchet marks and most of those are located on the devices and not in the fields. The fields are very smooth. The color of the coin on the obverse is a mottled mixture of light golden and light blue. The reverse color is light golden. Under good lighting the coin has very nice eye appeal and luster. I compared this coin the the 1969P quarter in my Dansco Washington Quarter album and its quality is much better than the Dansco coin [which has numerous planchet flaws].
This newest 1969P quarter has now upgraded my Dansco album

I have seen what you have described. Many times the appearance of a coin in the Mint Set cello packaging looks hazy. When you tilt or rotate such a coin at certain angles a hazy, blotchy surface contamination appears. It is very distracting. When the tilt or rotation continues the contamination vanishes.
Have you had any luck in removing this surface contamination without damaging the coin?

That thing looks like a 63 or 4 tops. Grading on a curve I guess.
