I would go at least AU. A lot of 1917 and 1918 have poor strikes. Yours appears to have weak oak leaves and die cracks but the crown is decent....
Personally, I would dab it with a q-tip after soaking (be careful not to rub). I generally soak to get rid of any PVC and that doesn't take too...
It looks like it could benefit from an acetone dip (if you're comfortable using it)
Typically, if a coin has a lot of damage and/or discoloration, there is a good chance that anything that looks unusual is also PMD and not an...
Environmental damage after it left the mint. Probably acid
The numerous 1972 hub doublings drove me nuts when I was a kid. At the time the DDO was discovered, I was 8 and just starting to get serious...

To respond to your snap judgement, I was able to find data on copper and 90Cu10Ni and the following common acids attack copper but not the copper...
What do you think caused it??
Sorry, but it's just a quarter that suffered environmental damage after it left the mint. Worth all of 25 cents
I looks like a a filled die and mm. I have a couple with filled digits.
Nice. A quick acetone dip may get some of the dirt out of the cracks without affecting the color. It's OK as is, however
But what happens when a number of different topics interest you? :) The more I read, the more areas become interesting. I drew the line at...
It's going to be 6 figures and the first number won't be a 1
From your OP, it sounds like you are still trying to determine which area(s) to collect. The Sayles Books are great for this. There are 6...
Separate names with a comma.
