Yes, that initial bottle flipping for ridiculous prices is something we observere very regularly. It is often the case for “hyped” releases like you mentioned the Folio 5, some Highland Parks and so on. Actually when looking at the highest value losers most of them experience exactly that. Prime example is the whole Game of Thrones series. The Lochnagar House Baratheon dropped from over 400 Euros to 30 Euros!
