I have a collection of 15 vinyl records on how to speak Japanese from the United States Armed Services Institute. An organization that closed its doors in 1948. These records are at least 75 yrs old and are 1st edition. In addition to being released by an organization that no longer exists. I have found no other collection of this,( the closest being a 2nd edition for sale on Amazon) which leads me to believe these are very rare, maybe the only one in existence. Which leads me to wonder, are they valuable? If so, how much? I also have the original box they were shipped in. Pretty beat up but still intact. Don’t know if that changes anything but I’d thought I’d include that. Thank you for your time.
