Right above the 13, it appears to be engraved with 5/28. That could be part of the date 5/28/13. It probably isn't the date of manufacture, it is most likely given as a gift to someone. I've seen wedding dates, christening dates, & birthdates all engraved on spoons before.

Are you able to ask the previous owner if the date 5/28/13 is meaningful in some way?
