Yeah I've been weighing coins for a while and the scale is brand new
Remember coins are made of metal just like an old car body rusting away in a field.
All more commonly generically known as Environmental Damage.
Just Enviromental Damage. It is an old quarter exposed to the elements. I have seen thousands just like yours when in my Metal Detecting finds.
What type of areas do you generally find the better coins?
In the grass.. Fresh drops. Maybe there for a few days. For example. I can detect a certain grassy field and find nothing. A week later I go to the exact same area and find like $2.00 in Quarters, Nickels and Dimes and maybe also a ring.
Happens a lot. Those coins would not suffer Environmental Damage in a short period of time.
But coins that are buried for years get bad.
Here are examples from my finds that were buried deep -
Actually.. I think it does. You need a few years for the Cupro-Nickel to tone to a darker color from what I have seen in my 10 years experience in Metal Detecting.
So the eating away of the metal will vary from location to location. This excludes wear such as if it was found at a beach after long exposure.
I believe copper gets affected greatly with Ph levels below 6. I'd have to try to find some info on cupronickel alloys but I would guess lower than copper.
