We understand that it can be disappointing if your submission was declined. Our experts take object submissions and value each item based on multiple factors.
One of these would be what kinds of other similar objects are currently listed in upcoming auctions. If the expert feels that there is too much competition between objects, they will not accept any further submissions until some slots free up. You can re-submit at a later date, and your object can then be reviewed for approval again. This is in an effort to ensure that your object will have the best possible chance to sell on Catawiki.
Another factor is that we have a minimum estimated value for a submission. If the object does not meet this expectation, it does not get included in an auction.
