I came cross this 2005-P Kansas State Quarter tonight from a bank roll. The edge looks like silver.     However the weight is not much difference, it is about 5.77 grams. Any advice? Many thanks!

Plated after mint. Probably silver or platinum. John1

I agree that it was probably plated, a lot of State Quarters were plated in the after market in an attempt to make bigger sales. In the future you should not use the compression type of paper clip to hold coins together. If they were valuable coins, you can severely damage them and reduce if not destroy any value that could be attributed to them. In fact, you should not contact any coin with a metal implement (pliers, tweezers, etc.)

Thanks John and Dearborn, that explains why there is no change in weight. Can anyone identify a plated coin without damaging it?
I appreciate and I will take your advice to handle the coins, Thank you Dearborn.

"Without damaging it"? Like John1 said an XRF machine. you could inspect between the reeds on the edge to see if the plating missed and copper is showing through under magnification.
What I would do, is scrape the edge between the reeds on the edge, on the low spots, and look under magnifier with copper. I'm certain it's plated without doing any of that.
The fact is, San Francisco makes the S mint silver quarters, there's no reason for a silver blank to be in Philly mint to be struck there from the start. For that reason, you don't really need an XRF or to scrape the edge and look for copper underneath, silver blanks don't just move randomly from mint to mint unaccounted for, neither does gold blanks. they have better inventory control especially since the PMs were taken out of circulating coinage and it's different supply chain paths nowadays.

Simplest test is the ping test. Flick it in the air and see if it sounds more like a clad or 90% quarter.

Good analysis, Big-Kindom  but I still decided to give it a shot...I tried jacrispies's ping test, unfortunately I have bad ears and I cant tell the difference between silver and clad. I then tried Drop and Sound Test that I found on youtube - I lifted coin about half inch above my wood table and dropped it. This test works for me on quarters and dollars, it doest work well on small coins like dimes. Anyway, my conclusion is - this 2005-P Quarter is not silver! Thank you all for your advice again.
