Robert, a couple points of order first.
1. We recommend people read our blogs first and note we value most circulated coins after 1970 as face value.
2. We ask folks to limit requests for complementary appraisals to one or two per day.
So please understand if I’m slow to respond to your five.
As for your quarter, modern U.S. coins are mostly copper. It turns red, brown, or green with exposure to water and humidity. Either it has environmental damage, making it worth 25 cents; or, less likely, it’s missing the outer nickel clad layer and is a true error worth $20 give or take.
