I for some reason thought this was Team Bullis's or Plum69's coin so when I passed it around at an event in Concord last week I was mistaken.
Today I showed it to Phild31 and low and behold it IS his.
This coin is pure and simply the most useful coin/tool to have. I'll be making my own that's calibrated to my arm extension, and perhaps with a small bubble level one would not need to estimate where the horizon is for all the times you are not on a beach.
