During a large metal detection rally in Belgium, at the end of the day I had a very high pitched sound on my equinox 600, I initially thought of a token hidden by the organizers but it was a currency in 1880 silver! A Belgian Leopold II franc, but that's not all because this coin is a rather rare commemorative edition to celebrate Belgium's 50 years, so we see on the reverse the portrait of the first two kings of the Belgians. My Equinox 600 will always amaze me!
