Fr. 2011-B $10/$1 1950-A New York B-D Double Denomination
Grade: PMG Ch. XF 45

The rarest of the small size double denominations, and undoubtedly the most sought after. Who would ever think of an $11 bill! The combination ofa $10 FRN and a $1 silver certificate back, surely makes for the most unusual combination recorded on a single issue. The error note expert, HarryJones, estimates that only six of these have survived. As amazing as that seems, three pieces were available at the 1976 ANA. This statement wastaken from the Hans Schulman auction description:

This $11 bill, a double denomination, is one of the rarest and seldom offered of the doubles. It is one of the most conservatively graded note Ihave seen.

Current Bid: $ 18,000.00
Estimate: ($ 30,000.00 - $ 60,000.00)
