I found the same jacket in Phoenix and it looks authentic and could be 57 years old. It was worth the $50 I paid for it. I too am curious if there is any value to it. It could have been made in Korea but at that time we Japan was the big importer. Also Harley was always big on American Made. So, I don't know but I could put it ebay if I wanted to sell it.
Yeah, I'd probably take the first offer. I doubt if there will be many takers since it looks like something Richie Cunningham would have worn to a sock-hop.
