I use a microscope that helps see varieties better for me. On varieties I question I use the images of both normal/variety. If its idenfied, I keep them. On the example above it is a nromal coin with images from coppercoins. I use these for teaching aids. The side by side images trains the eye WHAT to look for and WHY it is different than a normal coin. I have these as easy references on my computer and like to share with others. You may wish to copy these for your image library. Right click can save the image or highlight an article including images and save to a word page. You can't remove the images, but you can print the information to make your own three hole binder for easy reference.
