Previously, I presented images of leaves using a flatbed scanner set to reflection and transmission modes for comparison. See those here. This post includes scans of a variety of common objects. My favorite is the back of the Lincoln penny with him sitting in the monument. Images are viewable in larger size. Each image square is barely more than 2.1 cm (0.83″) on a side.
Some of the following were suggested by readers of the previous post. Thanks to them for their good ideas. The left images of the first 7 sets used reflection of light off the surface of the objects. The right images of those sets used transmission of light through the objects. Some post-scan adjustments were made with image editing software to enhance detail.
