Authenticate Maker's Mark

I purchased a number of goblets as a wedding gift for my son. I was told they were from 1890 (which is already suss because the makers mark looks like Manchester silver co, which wasn’t founded until 1892). I started out trying to get exact dates on them, but now I have armature alarms going off in my head. One has no makers mark, though it says Sterling and 762 (a style number?). Some have a mark that if so poorly pressed that it is hard to identify. Some have stamps that are just confusing. Keep in mind that I am judging this based on pictures I’ve seen on line, but from what I can tell Manchester Silver in RI went through three company changes and changed their mark slightly each time. So some of the marks seem to have a cross that leans as it would an older piece, but the crown placement or detail level look like middle or late periods. I am hoping I am just really inexperienced ( as in UN-experienced) in this and completely misjudging the situation. If someone has some experience in looking at these marks, I would love a second set of eyes on these.
