Hello, I am very new to coins and their values to collectors. I have a 1984 Denver mint penny that seems to have an error of raised lines on the back, from the corners of the steps of the buildings to the edge of the penny, symmetric on both sides. Unfortunately this is a circulated coin, but I was wondering if it would still be worth more than one cent to a collector. I have a 30x magnifying lens as well as a 60x-120x microscope and the lines are raised, not scratches. It also seems to have eroded a tiny bit around the D for Denver on the front. See attached images. Advice appreciated!
