I think it was like $150 total one time cost to put antique plates on mine. No annual costs other than insurance. I think its another 75 if I want to put an old plate on, I have my Dad's bicentennial plate with the Liberty Bell on it that would actually be correct...
Good Morning
My grandpa used to save all of his old plates... From the 50's through 75... When he died they let my cousin Pete have them...
He eventually threw them all away... We weren't happy to hear that he threw them all out...
