Question
what is the difference in the color of the seals on the dollar silver certificate? I have two with green seals and I cant find nothing about them. One is a 1957 series S02766087A. The other is a 1957A series B89071707A. Both in good condition

Answer
Hi Georgie, Collector value of a note depends on date, series letter or signature and condition, including amount of wear, any folds, tears or stains as well as collector demand. There have been so many made of these that only the uncirculated ones (no wear) have any significant value above face value.
In general:
Federal Reserve Notes have green seals.
United States notes have red seals.
Silver certificates have blue seals.
The 1957 series were all blue seals and would be worth about $1-$2 with wear to around $4 if uncirculated (no wear).
You might take them by a local coin shop for a first hand opinion: http://find.mapmuse.com/interest/coin_dealers .
