"Coin Uno or Follow the Leader" thread or some of its spinoffs. That one is based on the country or date of a coin. This one is a bit simpler. Anything goes (coin, token, or medal, ancient or modern, dated or not), as long as it follows the same theme as the item posted before it. So if someone posts a coin with a bird on it, and declares the theme to be "birds", the next person has to post a coin, medal, or token with a bird on it. See? Simple. Simple, that is, as long as everyone keeps the themes themselves simple. So let's have themes like "birds" or "animals" or "aircraft" or "lions" or "mythical beasts" or "coins with holes in the middle" or "non-round coins". Not overly-complicated themes like "Massey Ferguson GC1700 Series Tractors", OK? Follow the leader and see what the theme in play is. If you can post an item with that theme, then you get to post a second item of your own to start a new theme. If nobody follows a theme within 24 hours of its being posted, then anybody is free to post a new theme.
