Thanks Again @JimmyD that is quite helpful. I think I'd be lucky to come across a DD severe enough to capture. But if I can see MD I should be able to see DD on some coins. I'll keep looking. I'll try and get a better shot of the mint mark, in the not zoomed in picture it looks bigger then a normal P mint mark and if you zoom on that it almost looks like a DD but then in my zoomed shot it's hard to tell.
