How much are FortNiteBR bricks worth?

Excuse me, could you please clarify the nature of the question regarding the value of "FortNiteBR bricks"? It's worth noting that Fortnite Battle Royale (often abbreviated as FortNiteBR) is a popular online game, and as far as my knowledge goes, it doesn't involve a currency or item system based on bricks that have a real-world monetary value. Could you be referring to a different aspect of the game or perhaps a misunderstanding of the terminology? If there's a specific in-game item or currency you're interested in, please elaborate so I can provide a more accurate response.
