@nikitakostovska,
Depends in what country you want to sell them.
What do you mean with Venitioan do you mean Morano glasses?
Are the wine glasses or drinking glasses?
Are they with or without a gold?
As a rule people with a dishwasher do not want anything with gold on.
Coloured glasses are out of fashion.
Look at e-bay to find the style between 5 to 30 Euro for one.
