Well I got an email back from The National Purple Heart Hall of Honor Here is what she wrote me I'll copy and paste it
Thank you for contacting the National Purple Heart Hall of Honor regarding the Purple Heart medal you found. Unfortunately, our understanding is the
Serial numbers were not registered to the recipients so there is no way of
Tracking the rightful owner. Perhaps your local museum might be interested
in adding it to their collection?
We are a NYS facility administered by the Palisades Interstate Park Commission (like a museum) and are not directly affiliated with the federal
Government or Dept. of Defense. Therefore, we rely on family, friends and recipients to share their stories with us.
Please help us spread the word about our mission to collect, preserve and share the stories of Purple Heart recipients.
Sincerely,
The National Purple Heart Hall of Honor Staff
