I posted this over on Forvm but thought a few here would enjoy it. http://www.theatlantic.com/technology/archive/2016/03/adrienne-was-here/475719/ 'Kilroius was here' indeed. Feel free to post your coins with graffiti.
The only 'graffiti I see on any of my coins (and even identified as 'graffito' by the sellers) are small, seemingly random scratches...But what do I know LOL
This stater of Sikyon has a Phi scratched on each side but the one on the obverse is weak enough to barely show on the photo. I wonder if it was the initial of an owner once upon a time.
Coincidentally, my Sikyon stater has graffito in almost exactly the same area as Doug's. It's so light as to almost not be visible, but it's definitely not a Phi, more like a rough square... Here's a C. Norbanus denarius with much more prominent graffiti that I really like and wish I could decipher. Actually, I don't even know if it's ancient, but if the ex-Haeberlin provenance is correct, then I'm guessing it ought to be at least a hundred years old .
This Phlious obol (it is AR, just very toned) has "P" scrached on the reverse. Phliasia, Phlious AR obol 400-350 BC 11 mm, 0.84 gm Obv: forepart of butting bull left Rev: large Φ surrounded by four pellets Ref: SNG Copenhagen 8-9 Triskeles Sale 9; Oct 2013 ex BCD Collection, not in previous BCD sales

The reverse of this denarius has a lot of graffiti and there is a teensy edge crack, but who wouldn't want a coin issued by Cassius? At least it is centered, with full legends.
