Need help, missing 5 kudos

I'm currently have 148/153 kudos from museum and can't seem to find the missing 5
I have already got my exp lamps from Orlando and the 10k exp lamp from the historian, evertime i talk to him its says "On second thought, you seem to have everything I've covered here".

all my display case item are in but i think its has something pottery since i always get them from dig. but I've have but pottery in already!

Any suggestions help, thank you
