Are 5 dollar and 1 dollar 'silverbacks' worth anything?

Answer 1

If you are talking about silver certificates then the answer is yes. On the dollar ones from around $2.50 and up, depending on condition. On the fives from around $7.50 and up again depending on condition, which must be fine or better on both denominations. The series date and signatures, as well as grade determine value. Also if it is a star note, there is a star at the beginning of the serial number. The older the better, the common 1957 series $1, has no real rare notes. Now a $5 1953B star note in uncirculated condition sells for $10,500 though. Prices are retails expect to get less from a currency dealer.
