Walter, This has been brought up before and is why I hate to hear the words, "it looks terrestrial".
This link pretty much sums up your question; http://www.bccmeteorites.com/pigeonholing.htm Tony Irving's Martian web site says a lot about these as well. In addition; Blaine Reed's new XRF gun if used properly might be able to put us one step closer to discovering these missing finds. I know I have three self find prospects that without Blain's gun would still be sitting in a drawer. More on these later.
