I've been working on several 19th Century Copper and Minors sets of South America. My primary focus right now is Argentina, Paraguay, Uruguay and Colombia. I'm having a hard time locating some key pieces I'm looking for. Any dealer's you guys can recommend that focus on Latin American coins would be greatly appreciated. I know of a few but I would like to expand my search horizons. I check eBay, Heritage, Stacks etc regularly but I'm curious what other online resources you guys use in searching for world coins... Thanks!
