No not the mannequin challenge <| sep |> Voluntourism ? I don ' t understand that either . Just give the money to charities instead of doing that . That doesn ' t help anyone . Such a white person thing . <| sep |> I will be ready in 5 minutes . <| sep |> Of course , I ' m saying you very likely have relatvies left in Ireland , and they ' re not that far removed from you after only 70 years . <| sep |> Salt water , along with the motions of the waves constantly washing grains of sand over the surface , is really harsh on coins . Spanish silver 8 Reales look absolutely horrible after just a few centuries in the sea . These coins can ' t have spent very long in the water . If they are genuine , they must have been in a sealed pot that was only recently broken . I think it ' s more likely that they were part of a treasure hunt for tourists , but never found . Is the stretch of beach where your friend found them close to any hotels ? If it ' s far away from any touristy spot , that should rule out my little theory . Unfortunately , without better pictures , it ' s really impossible for me to properly comment on the authenticity . Hoping to see some higher resolution pics
