Not sure of the right category so let me know if this is wrong. What are these marks? Thanks.

Hi,

Welcome to the Forum.

I think it likely this is one of the marks used by Tuck Chang of Shanghai.

See: http://www.925-1000.com/forum/viewtopic ... uck#p59058

The other mark would be the chop-mark that identifies the individual silversmith that made the item.
