It looks to me like your quarter has environmental discoloration. Were it missing clad, weight would be less than normal. Quarter weight missing one clad layer = 4.71 g +/- 0.347 g; missing two clad layers = 3.75 g +/- .467 g.
Thank you very much....I'm still new to all this stuff, I dont have a scale to weigh it yet but I am probably going to get one today since I have some other coins that I'm curious about as well.
Generally it's going to be on one side only. I assume that if it was missing both sides, besides being incredibly light, the pressure from the strike is going to make it look different than a regularly struck quarter. But we'll have to check photo evidence on that. This is what a missing clad quarter looks like. Compare the bright copper color with your coin.
Look for a scale which weighs to 2 decimals at least and takes AA or AAA batteries (easier to change)
It is not really that much lighter. Not necessarily. All of My missing clad layer errors look pretty sharp in detail.
I was only speaking of a coin missing both clad layers. If you strike a quarter with the same pressure as you would a 5.67 gram coin, with one that is now almost 2 grams lighter it may look a little different.
Here is a reference http://www.error-ref.com/missing-both-clad-layers/ What has not been seen, to my knowledge, is a full weight, fully struck copper core, although full weight missing one clad layer is known
I have seen that one. But that is a different issue. I meant a normal Quarter or dime with both sides missing clad layer.
