This security cannot be stripped, so no stripped figure exists for it rather than one that is zero. Stripping separates a coupon security into its individual interest and principal payments, which needs more than one cashflow to separate. Market statistics.
Amount outstanding as reported by Treasury, in its Monthly Statement of the Public Debt. The Safe Rate indices weight on a different figure, float-adjusted original par, and the two are not comparable security by security. The index figures are published per holding.

Where its rate sensitivity sits
All of it in one place. A bill pays a single cashflow at maturity, so its key rate profile is its modified duration of 0.060 years, sitting in the nearest bucket and nothing anywhere else. That is also why its duration equals its remaining term rather than being shorter: there are no coupons to pull the average payment date forward. A twelve-bucket chart of that would be eleven empty bars.
Against the money market curve
Priced 0.04 cents per 100 of face cheap to the curve on that day.
Shown as a price rather than a yield. This bill is 23 days from redemption, and inside a month the difference between its price and the curve annualizes into a number that looks like an enormous mispricing rather than the fraction of a cent it is: worst case across eighteen years, 1,435 basis points on a residual of four cents. Its yield above is unaffected and stands: a bill quotes on an investment-rate basis, which is the market's own convention rather than an annualized stub.

3 auctions
A CUSIP can be auctioned more than once: Treasury reopens an existing security rather than issuing a new one, so the same bond is sold again at whatever yield the market then wants.
