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 0.096 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 2.9 bp cheap to the curve on that day, 0.28 cents per 100 of face.
Not scored against its own history. The z-score is written by a separate pass, and a security needs twenty observations before one is meaningful, so a new issue carries none for roughly its first month. An absent score is not evidence that a security is fairly priced.

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.
