Well, let's see what @Conder101 has to say. Apparently, he knows everything about this sort of anomaly. Chris
I would be inclined to think that if both "Clad Layers" were missing there would hardly be any design on the coin. At lest very faint around the edge, the same as a "Thin Planchet Strike".
Yes to Environmental Damage I dug these up metal detecting - Copper looking due to soil, dirt and sand
Even a genuine missing clad layer quarter ( I don't think) is worth "hundreds". I doubt an offer was made.
plz look again at pics i sent a email to heritage auctions an he can back with a value of $250 to $300 if y'all don't believe ill prove it!!
Please understand that there have been a lot of New Member trolls on here recently, so that may explain some of the comments. Based on your pics, a number of experienced collectors and numismatists on CT have the opinion that your coin is not a mint error and have pointed out some reasons why. Many clad coins turn this color when buried; If the surfaces are copper, it would have had to have circulated for awhile without being noticed for it to tarnish to that brown color; and there appears to pitting on the front. Maybe it's an error, but a lot of things point to it being environmental damage. If you don't like the opinions you received, pony up the $20-$40, send it to PCGS, NGC or ANACS, and see what they say. If it turns out to be an error, feel free to post saying "I told you so". It will help the rest of us learn. But the overwhelming opinion is for you to save your money. So, either send it to be slabbed or be quiet
