Wondering about the year

I received a family heirloom that I am over the moon about.
Now I am just trying to find out what year it is from. If this is possible I will be able to find out if my great grandparents owned it or my great great grandparents.

It is from Reed & Barton. It is a coffee/ tea set. It is silver plated
There is nothing on the bottom except for the words reed & Barton & the # 100.
& on one of the pieces the word GILT.

I would LOVE any help with this
thank you
