I have heard of tooling, but have never seen an example of a tooled ancient, and known what it was. In the spirit of helping a noob, will people please post examples of tooling with their comments on where it is?
This is a page on Tooled coins, on Forvm: http://www.forumancientcoins.com/board/index.php?topic=53363.0
Or, look on Ebay for almost every early bronze being sold from eastern europe. There is a textbook worth of tooling there....
