Since this is a “old” thread with old in the title I don’t see a problem replying. The definition is value based.

An old piece of $#!% is just that and is worth the least.

Old School is the next; with an add-on value given for Old Skool.

Vintage commands the highest dollar.

I see a rare and component difference between Old School and Vintage.

Antique is the odd one as the price typically always exceeds its worth regardless of the dollar amount since the person buying it doesn’t care.
