Vintage musical instruments

According to a 2011 list from Vintage Guitar magazine, one of the rarest instruments is the Space Age chic 1958-59 Gibson Explorer, valued at $250,000 to $310,000. A 1936-42 Martin D-45 is an even greater find: this steel-stringed acoustic model could be worth between $250,000 and $400,000.
