8 track price guide, it's a work in progress.
While most 8 tracks that are "valuable" are worth a couple of hundred bucks, tops, for super rare and desirable tapes, one tape at least has sales records to back up its $6000 valuation. That 8 track is pictured to the left.
The album is Sinatra Jobim on the Reprise label. It's a Frank Sinatra album featuring Antonio Carlos Jobim. The story goes something like this...only a few thousand copies of the 8 track were made and sent to retailers. Some sort of disagreement led to the record label cancelling sales of the album and even trying to pull them from stores. The album was not released on any other medium, so the few 8 tracks that are out there are all that exists of this album, aside from the acetate - if it exists.
Over the course of the past ten years, I've seen two of these, both of them on eBay. The one that sold highest fetched $4550 in pretty scuffed up condition. The other was right around the $4000 mark. Both were opened and used. I would expect a sealed version, if it existed, to sell for $6000. Most 8 track collectors wouldn't shell out six grand, but a diehard Sinatra addict would probably love to have the album.
But is this tape the most valuable ever? It's the highest priced 8 track that I've ever seen, by far. There could possibly be something out there that a collector or fan would pay more for, but right now there's nothing I've seen or can think of that would come close.
