1837 50c - Fake? Or Genuine?

No one thread is going to address all that, but there are plenty separate ones to be had. As Dave said, take a gander through the Photography section. There are years' worth of posts from how to get the best lighting to where to get the cheapest lenses to play with, to what sort of cameras are best and what their settings should be. Axial lighting, sunlight, other lighting methods. You could spend days in there making a list of pointers and shooting methods. Once you've read a bit, if you have questions you can certainly open a thread with them and get plenty of suggestions.

A phone camera can get excellent photos, you just need to play with the settings and lighting.

If any of you were in my area I'd be happy to help set up for photography, especially if I got to see large bins-full of coins while doing it. I love trying to get the best images, even tho it ends up hurting my back after a while It's the tedium of rolling through a hundred or so, taking 4+ each specifically for sale on ebay that gets to me.
