Typically it is up to the consignor, and your options should be in your contract. Always read your contract carefully - while most collectibles auction houses will offer the option return or try again (whether by rerunning or other arrangement), it's not unusual for a general auctioneer to keep items that don't sell - but again that is not typical for AH's specializing in collectibles.
In our case, most consignors opt for re-run
