Very nice coin and I believe 100% that you found it. Unfortunately it won't make the banner for several reasons. First of all, the find, although 'recent', was not recent enough. Also, the post was very likely his first ever post so that automatically negates it for consideration, and finally, the staged in-situ pic. That is NOT to say that there is any devious thinking behind a staged in-situ unless the users intention was to decieve. I don't think this is the case. Maybe the more accurate term would be 're-created' in-situ which I have no problem with.
Thanks for sharing the coin though! It definitely drool-worthy!!
