MUST be organic. You didn't seek out old gravestones, not a historical site, you're not an archaeologist. You MUST have stumbled on it (in a cemetary or other religious burial ground).
I have seen 1717.
It's fascinating stumbling upon old gravestones with centuries-old dates! 1717 is incredibly early, and it must have been a unique experience.
