Catawiki made me sell chinese antiques from the 18th century as 19th century and did not care about proof of age or comparable items (luckily buyers have a better idea of the item, as the selling prices show). An other object was under review for more than one month! After several emails, nobody cared and I deleted it from the list of submitted objects. A new one is already in Limbo for 3 weeks again... Pre-Columbian Objects from a collection established in the 1960's... said to be fake !? Two month later I resubmitted them. This time they got accepted... by the same expert... I have seen items where more then ten years of experience screamed: fake... sell for hundreds of dollars! Hands off this platform! If you are a seller and you are sure of what you got to offer! When you are a buyer, you either get fooled by them, or find a nice antique for a small price, because they have no knowledge of what they sell or knowingly sell everything including fakes, in most of the antiques departements!
