Just a question - are you scanning your coins or something? I noticed on your love token post that the pictures were the same. Very grainy. I'd love to see clearer pictures of both the love tokens and these doubled dates.
Nice find! And the correct spelling is Uruguay. I was there in 2009 in the city of Sacramento. Took a ferry there from Buenos Aires Argentina.
Using a iPad and a enhanced vision Acrobat LCD. When I crop them with the iPad it makes them grainy. One day I plan to get a camara and start getting good pictures.
