And what is not apparent in a photo of just the coin is the sheer size of this thing. It comes in at a stunning 70mm (2.75 inches) diameter and is a brick at 105.3 grams (3.71 ounces). I can not find any information on what metal it is made of, but it is a proof-like mintage (or possibly a true proof) with a mirror surface on the flat parts and frosted on the raised parts. A real beauty.
Answer: I don't know, but I do know where the design came from. This design is done from a photograph by Anton Croos of a bat moving through the branches (instead of just hanging). I don't have permission to reproduce it here, but here is a link to a blog page about bats that uses the photo with attribution. You will notice it is the exact bat and pose used here.
And did you go there? Nice page with lots of very good bat info. And in the caption for the photo by Mr. Croos one should notice that the picture is of a bat taken in Sri Lanka. Last time I looked at a map Sri Lanka was off the southern coast of India and no where near Africa. So... Did they use this bat photo with permission for the coin image? I don't know, but if I were the photographer I think I would not give permission to use an Asian bat on a coin representing Africa. And surely given the high quality of this photo he had a better bat picture around than this one for a coin image. And so there you have it, the origin of the image, but no answer as to how that image ended up on this coin.
So that is it for the Stop Ebola! series. From what I know I can say that these are rare coins (good from a collector's standpoint) and that they seem to have a bit of a mysterious origin and minting (bad from a collector's standpoint as origin and authenticity are key in collecting). Really cool additions to a bat coin collection, but not really sure how they fit in anywhere else.
And, since I have made it clear that this final coin is large, I will end with a photo of it next to a US one cent coin for comparison. Which would you rather have in your pocket? (trick question, as the big coin is worth a whole lot more than a cent)
