Hi. I have received a Z Gauge Marklin Train Collection from overseas. If I am interested in selling the collection in the future, is it better to have it auctioned off at n auction house that specializes in trains, consigned at a auction house for trains to sell over time or outright to store buying collections. I have completed some research and received some offers from stores. There are too many items to sell individually and they from the 1980s. They have not been used in 30+ years. Thank you for any advice.
