Alabama war defense bonds

[Texas Jed]

I was in a shop today and came across a hand serial numbered Alabama war defense bond with all of the signed bond reciepts except for three. The date on the bond was 1861. I didnt think about at the time, but I did not right down the signatures name. If my memory serves me right the bond amount was 500.00. The signatures on the bond reciepts were the same as the large bond the recepts were attached to. The item is interesting to me

Can anyone tell me what the reasonable amount would be for an item of this type.

Thanks
