   People are now alert to the possibility of Moon and Mars meteorites -- in   
   particular, private meteorite hunters are very much aware that verified   
   Moon and Mars meteorites are *much* more valuable -- so a meteorite not   
   identified as such almost certainly isn't one.   
      
   So yes, you've probably got a piece of asteroid there.  The details are a   
   bit fuzzy in places -- notably, there is a long-standing discrepancy   
   between the distribution of meteorite types (about 70% ordinary   
   chondrites) and the distribution of asteroid spectral types (only a very   
   small minority reflect light like ordinary chondrites) -- but that's   
   clearly where most meteorites come from.
