You sent me on a wild robin chase there...
Had never seen such a robin. (Only knew the European ones.) Took me 10 minutes to find Australasian robins. So, am I right to assume it's one of these https://en.wikipedia.org/wiki/Scarlet_robin ?

For your question: I have 17 different tokens. But for only 3 of them I actually know how & why I got them: PAL, GSB & CCC.
Don't really have a clear favourite, but if I have to choose, CreativeCoin (CCC) would probably be it. Mostly for the focus on active creation of content & unlike PAL there is a clear focus.
