The frontier between ''vintage'' and ''junk'' ?

We have a Winner! Junk that has become treasure.
The ad for a pair of XXXXXX speakers. 1968 famous.. look closely, chips, damaged.. Hmmm a little rough for the asking price of ONLY $120,000.00
Yes $120,000.00 NOT a misprint. Speakers the dude probably found at a rummage for $100. are being suddenly transformd from "junk" to "Treasured antique". I do not want to get into trouble here for 'dissing' someones ad so just say you gotta search for it. but not many have a price tag like this one.

I always find great deals at thrift stores, usually people get rid of his vintage stuff to buy modern hifi. They didnt know the treasure they got in their hands.

The word, which is largely a derivative from the world of wine, is overused simply in the name of salesmanship. In terms of how to define it, that is nebulous. That being said, I did snag a pair of speakers off of Craigslist that I would qualify as vintage: large Advents circa 1975.
