also, i would say, there are many different qualities and styles of Murano,
i think , once you start listing a few at a time, you will attract the collectors,
and hopefully get a fair price, list with plenty of pictures from different angles,
describe them fully, and dont sell to people who ask 'have you got a buy it now price?'
Do some research on Murano , look regularly at other Murano items for sale on ebay for info,
maybe ask a good local auction house to visit you, (usually free) they will give you some ideas.
