[QUOTE="Sallent, post: 3203829, member: 76194"][USER=98181]@Silverlock[/USER] flow lines is a good guess. Could also be the way the flan or dies were prepared. Some coins have flan preparation lines or adjustment lines: [ATTACH=full]829770[/ATTACH] Coin from a recent JA auction And other coins have naturally rough surfaces from the way the dies and flan were prepared, or from die erosion. [ATTACH=full]829771[/ATTACH] Example: the obverse roughness from one of my Litras is a common feature due to die erosion, but may be mistaken by some as corrosion or post-mint damage. And there are a whole other host of explanations for lines and marks on coin surfaces depending on the type of coin: for example, die rust, cracked dies, worn dies, double strikes, flow lines, adjustment lines, post-stike finishing (filing) by the mint workers, adjustment lines, etc. The point is that OPs coin could have a dozen things that could explain those marks that may not be indicative of anything neferious. To jump to the conclusion that it is a cast without explaining in detail why [USER=24314]@Insider[/USER] thinks that is the case is unfair to OP...especially considering he is not exactly a proficient ancients collector. I hear what he says, he's seen weird marks in cast forgeries, but those marks don't look to me like the typical marks one would see on a cast die that was damaged prior to it hardening. Another thing that makes me believe not a cast, I don't see the soapy look or the softness in detail (looks like normal wear to me) and I don't see the pattern of cast bubbles or die bubbles you see in casts, but rather irregular pattern typical of corrosion pitting and porosity one would get on a genuine coin during burrial. Not to say OPs coin couldn't still be a forgery, but I'd be shocked if it was one. My best guess, could be some sort of flow marks from die wear or erosion, or flow marks exaggerated by irregularities (non-uniform surfaces) in the flan made during flan preparation...but I won't say for sure as there's still a lot about the ancient minting process I still don't know (and I'll readily admit to that).
