1. How do you get rid of the dark lining shadow of the lettering. I see the doubling and y'all see black shadowing. 2. The shinny glare how to dim a light just enough that you can see more of the futures of the coin. 3. How close should you be to snap a photo of the coin and 5x, 10x, 20x, 30x or more.
1. Could be wrong but sounds like too much back lighting to me. 2. Shiny glare sounds like camera too close or maybe a built in flash making glare. 3. Maybe the zoom setting on your phone could tell you how much magnification you are using? Practice makes perfect with photos and each person's phone is unique. Keep at it.
