Yes and no:

• The marketplace is restricted to automated processes.
  
  Only fresh new tokens can be pushed to a shop, and the only place that allows you to enter information for the tokens in the marketplace is the tokens manager, in the latest steps before deployment.
  
  Once a token is pushed to the marketplace, and someone buys it, it can't be pushed again on a new shop. It can only be resold through an auction.
  
  
• The auctions center is available for reselling tokens.
  
  
  • You can start an auction by selecting this option after the deployment of a new token.
  • After purchasing a token at a fixed price in the marketplace, you can start an auction for it.
  • If you acquired a token on an auction, you can start one on your own for the same token.
  • Just consider that non-unique tokens (those with an issuance above 1).

The next considerations should be taken on auctions and token uniqueness:

• An auction can only be started for a unique token or a copy of a non-unique token.
• You can't have more than 5 live auctions for copies of the same non-unique token.
