Medal collecting can be very specific and the above guides are intended as an introduction.  Expert advise is often needed since the guides can not address every possible question - especially about a specific medal you may be looking at.  If you found this guide helpful, a Yes vote is appreciated.  This will help me gauge the level of interest in this and similar topics for further guides.  Please visit my blog (http://blogs.ebay.com/tsa-li) and/or guides for further information.  Thank you for your visit!
