[QUOTE="Alegandron, post: 2978888, member: 51347"]Thank you... I really have more pedestrian / circulated / used coins. :) "Flow lines" remind me of what happens in injection molded plastics...plastic flows into the molds and do not completely blend, thereby showing "flow lines". It is more of a MATERIAL imperfection. (manufacturing background here). For metal (silver), I view them more lovingly as [B]"stretch marks"[/B]! Because, that is more the resultant process on the MOLDS... The molds are stressed, with the surface of the mold being [I]stretched[/I] over time, with multiple strikings beyond the molds' intended usage life. Most of my collection is from the BCE Period: Republican Rome, Greece, and Asia mainly AE). Generally, fewer coins were made. They appeared NOT to produce the monster-mass scale of coins as in the Roman Empire Period... so many of my Republic-era coins' molds do not appear as stretched as many of the Imperial molds. I have a few [I][B]STRETCH MARKS... :)[/B][/I] [B]REPUBLIC:[/B] [ATTACH=full]732518[/ATTACH] RR Anon AR Denarius 115-114BCE Rome mint 19.52mm 3.82g ROMA X Seated r on shields spear birds she-wolf Romulus Remus Cr 287-1 S 164 Maybe some Stretching around Obv nose and mouth [B]IMPERIAL:[/B] [ATTACH=full]732520[/ATTACH] RI Lucilla AR denarius Juno seated flower child in swaddling clothes Seaby 36 [ATTACH=full]732521[/ATTACH] RI Augustus AR Denarius struck 2 BC-14 AD Caius and Lucius Caesars stdg shield spear S 1578 NGC4276216-007 Looks like the REVERSE MOLD was heavily over-used[/QUOTE]
