QUERY: IMAGES OF COIN EDGES AND MINTMARKS SOUGHT

I'm preparing for a presentation on April 24th to a group of young numismatists at the Dulles Expo Center coin show in Chantilly, VA. I built some slides for a "Collecting 101" presentation where I'll define some basic numismatic terms including mintmarks. I also discuss the "third side" of the coin, the edge.

Perhaps one of you can help. I'm looking for images of the following: closeups of U.S. coin mintmarks (P, D, S, O, C, CC, etc) and a couple lettered edges, such as the 1793-1795 cent “ONE HUNDRED FOR A DOLLAR” or the Bust Half Dollar, 1807-1836, “FIFTY CENTS OR HALF A DOLLAR”
