Interested in macro photography, specifically numismatic photography (coins).

My coin photography consists of a Canon EOS Rebel T3i, Asahi Pentax Auto Bellows and Rodenstock Apo-Rodagon-D 75mm f/4 duplication lens, all mounted on a modified Bausch & Lomb microscope A stand.

I'm still new to photography and always want to learn more, so any feedback on my images is greatly appreciated.
