I guess they couldn't resist that white label, similar to early Riverside, some OJC have. It makes those "Sound of Sonny" looks like the real deal, especially with a blurred Ebay picture... please add the typical Ebay "more money than brain (and eyes, and knowledge)" behaviour, and you have an explanation of those 500 $.
Try $599, not $500:

I have seen this ebay listing many times...is it a sincere mistake ? or a very bad scam ? other reissues are lsited in the price range ... anyway, nobody "bought it now".
Somebody bought it!
