Antique P.P.S No. 11 Cast Iron Skillet Gate Mark For Sale

Does have a line on the internal rim. It can be seen on both sides but it does hold water and not leak. I am thinking it is from manufacture and not a crack, but I am not 100 % sure. Not really where a crack would show up on these from damage or impacts. It does wobble and spin from the gate mark. Some pitting. Shows wear, see pics. Looks to be restored.
