Depends what you consider as expensive. For example we don't have 25'000 USD ships like star citizen (yet )

The are also in beta and their product cost much more. The game has not the same scale of course. But using the blockchain uses true ownership meaning comparing to other product things are limited, verifiable and transferable. So 1100 BCY for an item that has a limit of 300 units I think it's not that expensive I guess.
To compare some card in Moonga (our previous game) are sold on the black market for about 1000$ a piece.
