For Puerto Rico chip collectors, you might want to compare this $5 chip with a similar PR CIC $1 chip from San Juan Quality Royale. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190163984064&ssPageName=ADME:B:DBS:US:1123

Just my personal opinion but I believe that the $5 Dupont Plaza center insert may have been muled with the outter ring of the very similar $1 Quality Royale chip.
