Here's a link to the pattern coin section on a website I write guides for. It currently has some half cent and one, two and three cent patterns. The site's owner, Daniel, is still working on this section. http://coinauctionshelp.com/Pattern_Guides/patterns_home.html Here's a link to the forum for the website: http://coinauctionshelp.com/TPGS_FORUM/phpBB3/index.php I have some short guides written in the U.S. coin section, world coin section, error coin section and I made all the charts in the silver coin value charts section. If you would like to request a silver coin value chart for any of the countries that isn't listed, let me know and I can make one.
