... I found an interesting site that lists acronyms & abbreviations of fraternal organizations. It could be useful to ID chips or other exonumia. The link is below. It's worth a quick look & bookmark. The site is maintained by Rich Hartzog, a noted exonumia dealer & expert on 18th Century Slave Tags. It is also worthwhile to look at the information on Slave Tags on his web site. Ever seen one of these? Makes you think...
