Coins Online Auction: How does Catawiki work?

Catawiki is the worldwide reference place for Coins Online Auctions and online auctions of collector’s items. Today you can distinguish in the market of auctions on line two major players, the most popular is the site of Ebay that collects thousands of offers daily. To use a metaphor, Ebay is like a fish market where every single fisherman tries to sell his fish to the highest bidder.

However, since 2008 a new portal has been created that has literally transformed the way we manage our coins Online Auctions, we are talking about Catawiki Auctions that has made the negotiation more secure and reliable by simply introducing the concept of Supervisor.

The Supervisor is nothing more than an expert in his category who has the task of estimating the object proposed in the auction and validate the auction proposal. In this way, the buyer has the assurance that the object awarded has actually the declared value.

To return to our analogy, it is as if there were at the side of the fisherman a guarantor that confirms the origin and quality of the fish sold.

In addition, Catawiki acts as a mediator between the seller and the buyer, technically has the item awarded sent only after receiving payment from the bidder and pays the due to the seller only after the proper delivery of the item concerned.

All this has contributed to the exponential growth of the platform, making it today the safest and most reliable in the field of online auctions of collectibles.

Commissions on Catawiki Auctions

Just as with real auctions, a buyer who buys an item in an online auction on Catawiki must pay an auction fee of 9% for each item awarded. In practice, the costs for those who buy are summarized as follows:

  • The cost of the item, in other words the price at which the auction ended.
  • The auction fee of 9%

The buyer’s commission is a small fee to be paid to support the service of object verification by experts, as well as the entire platform. An expert’s report, for some rare or valuable items, reassures the buyer that he can then concentrate on the auction completely and without any concerns of any kind.
