Hi All,
I don't know either! I bought this medal like I said in the mid 1990's, thinking it was an original. It came from a big Japanese collector on Long Island NY who reports he aquired it in the early 1950's. His collection also included a Marshal's Badge which he sold to two gentlemen from Japan in the mid 1970's for $5000. The gentlemen from Japan didn't believe the Marshal's Badge was authentic until they saw it. Anyway it's anyones guess if this particular Great East Asia War Medal is authentic or not. I realize there isn't any definitive test one way or the other.
Thank you,
Tom
