Mccoy's Graystone line has such beautiful colors as can be seen on this teapot and two matching pedestal mugs!
Teapot is marked on bottom: 1418, McCoy, Lancaster Colony (mark), USA.
Mugs are marked: 7112, McCoy, Lancaster Colony (mark), USA.
Teapot and mugs have no chips, no cracks -- mugs have very minor crazing inside bottom, teapot has a few typical McCoy pin pops -- not detrimental in any way. Beautiful set!
