"You're just too good to be true, can't take my eyes off of you..."
Soooooo hard to pick just 1 isn't it? I like the uncluttered designs and ones which say something about the Chinese as people... at least as far as I what I imagine their style, outlook and humour to be. And yes, they have to be pretty of course!
Gold - 1983
Has to be my favourite overall. This is the "sovereign" of Pandas, they could've stopped with this mouthwatering design. Truly a beautiful coin, the best fur of any bear and I love the understated frosted bamboo blending with the background. Big and confident golden bear. Incredibly it appears as though there's two different frosting types present, matte background with shinier foreground. Year 2000 design gets an honourable mention too.
Silver
It's such a close call between this... (Chinese kitschy design with sufficient elegant simplicity for the perfect blend).
this, (putting her best foot forward)
and this. (keeps me looking!)
However fish has asked for the favourite one so I'm going to say that these are 1st, 2nd and 3rd in that order. Just.
