You need this specimen to be evaluated by a university meteorite lab. ASU ( Dr Laurence Garvie) , WU ( Randy L. Kororev - Washington Univ.) , Tony Irving, a geochemist and meteorite specialist affiliated with the University of Washington in Seattle, Alan Rubin, UCLA tel:310-825-3202 mailto: aerubin@ucla.edu. and several others could confirm what this really is.
One young graduate is actively looking for meteorites to classify, Daniel Sheikh at Portland State University. It will cost about $350 and the lab will want to keep a small piece and a thin section. danielsheikh68@gmail.com
If this is a Martian meteorite it could be very valuable. Documentation needed.
