I Have Received (Partly) Non-transferable Tibia Coins For Selling a Character. Why?
Tibia Coins you receive from selling a character might be non-transferable up to 120 days after the auction has ended. This feature was implemented to prevent fraud cases. For this reason, it is impossible to exchange them for transferable Tibia Coins before the given time.
The exact date when non-transferable Tibia Coins are converted in such cases is determined by the system depending on a rather complex algorithm with parameters that can change.
