different items are considered antiques at different ages- some things are sellable as antiques as young as 20=25 years...other items do not reach (antique=ism) until well over 100 years old- it is all relative.
some things which remain easily obtainable are considered vintage instead of antique- it seems some items only get the classification when it reaches (rare-dom)...regardless of age...
everyone has their own ideas about what it means- but if you go by definition---
i'm an antique....from the past-
