Hi, I have a $1.00 silver certificate that has a blue star before the serial number which is 98377442A. I have never seen a bill with a star instead of a letter before the serial number. Anyone have any input on it's possible value? The condition of the bill is only fair.

I also have several silver certificates with serial numbers starting with an X. The highest # is 64608693. Also, all bill are from 1957.

Thanks, I appreciate any info I can get on these unusal bills.
