This listing is for what appears to be an authentic McCoy swirl pot. Please see the following website for details on the authentic McCoy markings and the pink swirl pots: http://www.mccoypottery.com/mark.html#mccoyusa The piece appears to have some glaze impurities, specs, or chips (please see photos). The color appears to be black satin. I haven’t seen any of this color on the web, but the same pieces of different colors generally seem to be between $15-$30. I hope it is authentic. The name marking looks to be authentic, but if someone of the day made a new mold, I don’t know. I spent too long researching this (1/27/2024).
