Many vintage & antique Coronation mugs are just the right size for coffee. The smaller ones can make great Expresso cups and the larger ones are great for Cauppucino or Latte. The patterns on Cornation mugs are so varied that you can usually find one thats just right for you. The older antique china ones, are in my opinion particularly pretty and come in a range of colour patterns.
Get one and you may find that you get hooked. My personal collection of vintage & antique Coronation Mugs probably numbers over 60 now and still collecting. Vintage and antique coronation mugs for sale
