Yes they can.
Please see below reply from Mirade1 and refer to the TibiaQa question2 - What's the differences between a golden crown and Gilded crown?
From Forum:
"No offence, but I think thats a terrible idea. Those items were bought by players for extremly high sums and they are super rare as only a few exist. Don't make those trophies worthless by putting them in the tibia store. This is the same thing you did to the pharaoh rares, by adding them as trash loot into some bosses. You just screw all collectors.
Just to avoid misunderstandings: Gilded versions (of the golden replicas handed out in past Tournaments) are already available for Tournament Coins in the Tournament Store. They can be bought by anyone who has enough Tournament Coins to afford them. The golden replicas (which are the ones awarded to the winners only and which can be traded between players) will not be available in the Store."
