There's something funny about those coin sets - the up close image of the 6 coin set seems to show that only 1 or 2 coins are actually "special" Year of Astronomy coins, and the image of the 2 coin set shows only 1 that is a Year of Astronomy coin, albeit both are different coins to those in the 6 coin set.

Does that mean you have to buy both sets to get all the new coins - any collectors here who may be able to shed some light on this?
