WTB: 2009 $10 JC-B block FRN

Desperately seeking a series 2009 $10 JC-B block note in CU condition.
Will consider a circulated example, but really really want an uncirculated note.

For those unfamiliar with modern US paper money, the “block” is the combination of the serial number prefix & suffix letters. This example is a JK-B block.
