If your bill states that it is a silver certificate and the date
is definitely 1933 rather than 1934, you will need to have it
authenticated and appraised by a couple of dealers who specialize
in rare currency. 1933 $10 silver certificates are very scarce.
Retail values for genuine bills can exceed $4000 which is why you
should get competing evaluations. I urge you to be very careful
with it!
