I have an antique fruit knife which eBay removed as I need to send by the 'age verfified postage'. However, I can't get any options for postage up as it only shows me simple delivery.
I have just tried this on our other account eg fruit knife under cutlery silver/silver plate - I am assuming that for an antique one this is the case? Here it did not offer us simple delivery but under our primary service you need to click the three dots to the side and change service. Towards the bottom is the age verification service offerings from RM picture below shows.
