The only $10 US stamp still in circulation today is Scott #4720 - from the 2012 Waves of Color series of 4 values ($1, $2, $5, and $10). It is still available from the USPS on-line store and at some of the larger post offices.

The new 2022 Floral Geometry stamps came out in June - #5700 $2, and #5701 $5. There is no $10 stamp in this series.
