My grandmother left me some things when she died. Im sure some of the stuff is very old. (My dad is 84, she was 95 when she passed) How can I tell how old something is, and its value? Here are just a few things that I have. I can post pics if that would be helpful

Wicker tea cart

A doorstop(its a boxer dog)
A bunch of china
