Dutch style spoons???

My grandmother left these to me when she passed,I know nothing of them and can't seem to find any information on them anywhere. The only information I can give is my grandmother had them as long as I can remember,my father said he remembers her having them when he was a child and he is 67 yrs of age.my grandmother was 88 when she passed! I can't find any mark that I'm aware of on the spoons that could point me to where they where made.any information about them where I could research them would be great.i also unsure of the type of metal it is.
Thank you for the help!
