I just got my newest coin from Quartermaster and wanted to say "Thank you". The letter with it proposed some interesting science that was beyond me so I had to have my grandson explain it to me...
Hey! Don't leave us hanging dear old boy. What did the little fellow say? What coin did you receive? "In Cod We Trust" coin perhaps?
I got a Wyoming quarter with PETRA.FLAVUM counterstamp. The sciencey stuff in his letter went whooshing over my head completely, as I suspect he knew it would.
