I do not know much about antique coffee/tea sets. Let me know if you have questions and I would be happy to answer them or provide more photos. Condition looks good to me. I polished it a little to check and did not find any dents nor big scratches - just normal tiny wear in my mind.I did nothing with the insides of these 5 items. Check the photos for exact description. NOTE: One of the pieces which I believe is the waste bowl has a discoloration on the bottom.
