8 Zodiac by John Cuffley portmeirion pottery stoke on Trent mugs
All have interior staining. Some have superficial cracks around the handles. Aries mug has a large chip on the base. Cancer mug has a tiny chip on lower rim.
Scratching to the matte black mugs is apparently as well.
Please note mugs are from different collections/eras with different bottom stamps and slightly different sizes.
