I have made it clear the sample is invalid. I do not know it to be from a Bigfoot but I keep it for good measure as there is that possibility as the collection method used was designed for that purpose. It will be tested with the next sample to be collected that I know is a winner.
Thus ignoring all the points already brought up by me and by the other posters. Still no explanation for your reluctance to do testing (for free), and your total unwillingness to explain how waiting for a second verified sample would mean anything in terms of your first sample. Also you are again not addressing the enormous difference that was already pointed out between the concepts of "invalid" and "valid but not Bigfoot."
Again, I favor the idea that not testing the sample makes sense only in the Schrodinger's Cat sense: untested, you might have a Bigfoot sample, thus allowing you to construct a big, exciting story around your possession of such a sample. Tested, it will ruin the story, or at best, make it a relatively simple, fact-based discovery of another unknown species.
When I was a kid, I found a rock that I believed might be a meteorite. It was very exciting to me, and therefore it probably served me better to never have it examined or tested by an expert. In retrospect, my odds are strongly that that it was only a pebble. Given meteorites have been shown to exist, I had a better chance of my "sample" being real than you do.
