AG Schultz Creamer and sugar bowl

Hello all, wondering if these (yep, they’re grandma’s!) are worth insuring.

They’re AG Schultz, that is about all I know about them

I don’t have a pic of the mark, but its the AGS ‘hand’ in profile mark without the word ‘made’ in the middle.

Any info you might provide will be greatly appreciated.
