I am looking at a 1928 A series Silver Certiicate (dollar bill) with the serial number B75858963B. The Secretary of Treasury is A. W. Mellon and the Treasurer looks like N. O. Wooding. There is a number in the lower right corner, C 1473 and it has a blue crest on it. George Washington face is in the center.

Also I have another one dollar bill that's almost twice the size of the first one. Series of 1917 with a red crest. Serial number K99754104A signed by Treasurer Frank White and Register of Treasury I can not read. In th upper right hand corner is picture of nine men and the words Act O March 3rd 1863. Near the men is a letter D. Also on the right side is a letter and number D 168.

Can any one tell me what these bills are worth.
