I suppose it does not matter as long as the return on what one pays is at the current rate. If so, does this mean the current owners are losing money out of the sale?
The buying/selling price adjustments (sales in aftermarket) are based on the current interest rate fluctuation, like any bond product.
Hold the treasury to maturity and you get the face value and any coupon payments along the way. The stated yield when you bought it will be accurate.
