Cantrell- Posted 3 hours ago Share Posted 3 hours ago Is this 2000 quarter missing the clad layer or was exposed to some chemical process? I have read Learn Grading: What Is a Mint Error?- Part 4 along with looking at some certified NGC examples Apperciate your time and look forward to learning Link to comment Share on other sites More sharing options...
Coinbuf Posted 3 hours ago Share Posted 3 hours ago Welcome to the forum, do you have an accurate weight of this coin? Do you have a photo of the edge/rim? It is very unusual for a coin to be missing both clad layers. Sandon 1 Link to comment Share on other sites More sharing options...

Sandon Posted 2 hours ago Share Posted 2 hours ago Welcome to the NGC chat board. Your 2000-P Virginia quarter is simply corroded and is not missing its clad layers. The edge clearly shows the lighter outer layers. The coin's weight as shown on your scale is within mint tolerance for a normal clad quarter (5.67 grams plus or minus 0.227 grams), and the coin's surface is rough. The outer layers of copper nickel clad coins are composed of an alloy of 75% copper, 25% nickel. This alloy turns red or even black when the coin is buried in the ground or otherwise exposed to corrosive substances. Clad coins and nickels, which are composed of the same alloy, are seen with such discoloration with some frequency. Coinbuf 1 Link to comment Share on other sites More sharing options...

Coinbuf Posted 1 hour ago Share Posted 1 hour ago Agreed, a coin missing the clad layer would be underweight; missing both clad layers would be very underweight. Link to comment Share on other sites More sharing options...
