How much is 1000 NFT in dollars?

Excuse me, I'm a bit unfamiliar with the current market dynamics in the NFT space. Could you possibly enlighten me on the estimated dollar value of 1000 NFTs? I understand that NFTs, or non-fungible tokens, vary greatly in price depending on rarity, popularity, and demand. However, I'm curious to know if there's a general ballpark figure or if the value can be determined by a specific formula or market index. Your insight would be greatly appreciated.
