How much does a $1000 T bill cost?

Excuse me, I'm curious about the pricing mechanism of Treasury Bills, specifically the $1000 denomination. Could you please explain to me how much a $1000 Treasury Bill costs? I understand that the price is not necessarily the face value, but rather a discounted price based on various factors like interest rates and market conditions. I'm just wondering what the approximate cost would be for such a bill, considering the current market environment. Could you provide me with a rough estimate, or perhaps elaborate on the pricing process? Thank you for your time and assistance.
