Spotted a boarded up house yesterday. No keep out signs so I hit it todays with the V. First signal in the small side yard was a wheat. For the next 40 mins, every good signal is a wheat penny. I was there for 1 1/2 hrs, came home with 12 wheats and 7 early 60's pennys. No nickles, no silver, just PENNYS. Not really complaining, I just find this so incredibly odd.
