biokemist6 Bedrock of the Community United States 12437 Posts	Posted 06/15/2012 11:17 am Thinking that a coin "feels" lighter is a subjective measurement that is almost always wrong, an average person cannot discern a weight difference of 1 gram or less. Quantitative measurements are absolute and the scale does not lie(unless the calibration is off). As I stated earlier, this is environmental damage which is a catch-all phrase that can describe anything from fire damage to burial in soil. Report this Post to the Staff
jmkendall Pillar of the Community United States 1590 Posts	Posted 06/15/2012 11:25 am I agree it looks like hundreds of clad quarters I have dug from the ground. I don't know why but clad coinage almost always looks black. As do nickels. However cents and silver seem to do very well. Report this Post to the Staff
Buddy Rest in Peace United States 7075 Posts	Posted 06/15/2012 6:39 pm You know, you can always just hang onto it until you can find a decent scale. Or you can make a balance scale out of a Popsicle stick and a pencil. This will not give you the weight but it will let you know if it is significantly lighter than another quarter.

Buddy Rest in Peace United States 7075 Posts	Posted 06/15/2012 10:44 pm I have a newbie question. How do you know that this isn't a sintered coin? Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 06/15/2012 11:02 pm A coin struck on an improperly annealed planchet should be fully lustrous. Without luster, you have to assume environmental damage. Report this Post to the Staff

Shereeses New Member United States 12 Posts	Posted 07/19/2018 2:39 pm Hello there bugmanmiller. This posting was done quite some time ago but I'm curious to know if you still have this quarter and if you ever weighed the quarter on a better, more accurate scale. I too found a 1980 black quarter that was entirely smooth (edges and both sides) and significantly underweight. It appears to look different than the other black coin images provided to you. There is no damage to the coin (scrapes, scratches, knicks, etc). It still has nice detail. I searched the quarter and find this post as well as a couple others in different forums that provided much of the same description. I'm wondering if it just a coincidence and they are all results of environmental damage or if there's more to it!! Any updates from you or others would be much appreciated. Thank you!
