I have about 10 of these my daughter found. She works in a grocery store and I taught her how to look for silver coins. She spotted these quarters (found on different dates). Plated coins would be brighter, these are the same finish and luster as typical quarters. My bet is when they were bonding the three layers together at the mint (two layers copper/nickel - center pure copper) the copper center layer ran short and you only have two copper/nickel strips bonded together. The quarters also seem very slightly thinner than typical quarters. If I had a scale that could measure the weight it would help. Something to ponder....
I ran across one of these plated quarter. It was rejected by a mechanical coin counter repeatedly (even machines can tell lousy plated quarters). The plated coin was about 0.1 grams heavier than a normal clad coin of the same year and state (Kansas).
Mike Mezack just reading that name makes me pissed off! Some would call him a good business man. I call it scum of the earth marketing. Some day Mike will get his! Reed and a really pissed off Sparkles the Unicorn.
No visible copper on edge. The edge was probably plated over as well. The surface of the coin has an unusually high polish, almost proof like.
I know this is an old post, but I found a 2001-P NY state quarter just like these. No proof polishing is evident... not that there should be. I was intrigued by the suggestions it could be plated but my quarter's weight is way off... 5.67g is what standard business strike state quarters weigh, 6.25g for the silver proofs.... mine weighs 5.87g. Incidentally, nickel does have a heavier mass than copper so a solid nickel quarter should have a higher weight than a properly-clad quarter. Any ideas?
I came across a 2008 P Alaska quarter that also does not show any copper. Does it look plated? Imgur link: https://imgur.com/a/dsrfPvy
What does plating look like under a microscope? Unless they seriously botch the plating job, it looks like a solid piece of metal.
