I'm at 543,600 and that's with 90k shares bought at .26 several years ago.  I've bought throughout the years including some shares at .15.  I originally planned on stopping at 400k but then kept adding till I hit 500k.  At that point I was going to stop but the .06-.08 range was to tempting and added the extra 43,600.  I'm trying to hit 550k but that might take a lot longer than expected since I reduced my contribution to my 401k by 95% to buy physical silver coins/bars.
