2006 p Colorado, 2016 p Harper’s Ferry and 1965 Quarters

Hello everyone, I hope this post finds you all well and healthy. Today, I ran across 3 quarters from a box of quarters that I need help in identifying as either variety or error. The first is a:
2006 p Colorado quarter with copper showing
on both sides
Second is a:
2016 p Harper’s Ferry quarter that has a flat
Washington and flat edge circumference on
rev
Third and last is a:
1965? quarter that has a ring around the
circumference of the obv almost wiping out
Liberty, the date and “In and we” In God we Trust.
Three entirely different issues beyond my ability to indentify at this time. Could use some help. All comments are welcome.

I can't tell about the first coin... (looks corroded....need better pics)
But the 2nd and 3rd coins are damaged and not errors.
Agree.
Look at the edge of the first quarter. Do you see three layers? If so, that would support a diagnosis of environmental damage.
1 = environmental damage
2= damage
3 = damage
Sorry, but none are errors
First = Environmental damage
Second = Post mint damage
Third = Post mint damage
No numismatic premiums. Cheers, RickO
1: Environmental damage, probably from spending some time in the soil.
2: Just plain damage.
3: Just plain damage.
No value beyond face value.
