Unfortunately I can't take more photos as it is not my coin, but was considering buying. Thank you for your replies. I thought it might be fake for the reasons you've mentioned, though I must confess in terms of style it's pretty good.
This one is difficult to tell. The style does look good and a porous surface does not always mean it is fake. The planchettes themselves are occasionally crude and porous and will have rough or porous surfaces after being struck. This is more often seen in some earlier military mint issues but sometimes in official imperial issues as well.
My gut says it is real. I would like to see the edge though.
