My suggestion would be don't even think about listing them on eBay until you know what they are worth!
They could be worth £10 , a few hundred, or even a few thousand!
Just because you can't see any visible markings, doesn't mean that there aren't any hidden in the patterning! The patterning alone can be a signature of an individal artist / makers / manufacturer.
Plus, sometimes artists have hidden initials and even signatures in patterning on art pieces.
Truth hurts. Maybe not as much as jumping on a bicycle with a seat missing, but it hurts.
You may think you have pushed ALL my buttons, but you still haven't found the mute!
