post a picture of a coin (US,World,Ancients) with the next descending date,for example, if the previous post has a coin dated 2013 then you can only post 1 coin from 2012.once some one post a date you can only post the next date descending. any coin just as long as its the next descending date. To start, some one will need to post any coin dated 2013.lets see how far back you collectors can take it. to keep it interesting, please don't post 2 coins in a row. only 1 coin per date. so post your favorite. I don't own a lot of modern coins,so I will be a spectator to begin with.
