I cant find this one anywhere. The card that came with it references Milne 3107-8 and says the reverse is Homonia.
It's not a powdery green but it is very green. Like It was a green flan or something. I'm keeping him quarantined for 30 days following the Ebola protocols.
Very nice coin. It's impossible to tell from pics whether a coin has mineral deposits or BD, so be sure the seller has a return policy. I'm pretty sure every dealer on vcoins is required to take returns. As long as the green stuff isn't easy to dislodge, you should be ok. I can confirm the attribution: Emmett 3110.12.
