What is the value of a US 1 dollar silver certificate that has Lincoln and Grant on it?

The series date for these bills is 1899, although they were printed into the 1920s.

The date is difficult to find. If you look closely, it may be in very tiny print just before the Words "Payable to the" at the left of Lincoln's portrait. If not there, look to the right of the blue seal.

The long series run produced 13 different signature combinations. Most are fairly common, with values in the $45 - $150 range for a circulated bill and about $200 for an uncirculated one. The two rarer varieties are:

• Signed by Vernon and McClung and with date the to the right of the blue seal
• Signed by Napier and Thompson.

If you have either of these combinations you should have the bill evaluated in person.
