How much is a 1957 1 dollar bill (silver certificate) worth #V44299356A?

Have no idea what a 9.9 condition is for currency and notes are not graded that way. The note sells for $3 in grade very fine, $4 in grade extra fine, $10 in crisp uncirculated-63 and $15 in crisp unirculated -65. the values are an average of sell prices most dealers sell for less than book. Dealer pay 40 to 50% less. You note is not old enough to be rare or scarce. remember the date on a note is not the date it was printed but the date autherized or when there was a signature change. Only coins in this country must be dated the year struck, unless congress passes a special bill like they did in 1975. Most of the 1976 bicentennial coins was minted in 1975 with a 1976 date. hold on to it for the only place the value can go is up.

The 1957 $1 silver cert sells for $10 each in mint. You'd receive about $5-$6 when selling.
