Owned by: Jimi Hendrix
Estimated value: $2 Million
When Jimi Hendrix played "The Star-Spangled Banner" on the Monday morning of the Woodstock festival, he sealed his stardom. He also made his white 1968 Stratocaster an icon of rock history. It now resides in the museum that Microsoft co-founder Paul Allen constructed for the guitar after buying it at auction for $1.3 million. The combination of Allen’s obsessive curation and the guitar’s provenance, have raised the value of the piece to close to $2 million, say experts.
