Did some ebay browsing on some Britney Spears autographs from the 90s era. Came across these three autographs. All high priced, lowest being 700$ highest over 2000$ and all claim to be authentic and hand written. Would you tell any of these are likely genuine?

B1) At first, this didn't seem to me like her usual drawn heart (and position). But seems to be approved bei JSA. 

B2) For my eyes, this one seemed authentic, is high priced, but comes with no third party authentication. It has a nice background story written though. When B1 is authentic, B2 didn't seem farfetched to my eyes. So i was curious and asked a QuickOpinion from PSA on that auction. They gave me a result within 1 hour. Answer: "Likely Not Genuine". 

B3) Last one. This one is priced over 2000$, is encapsulated but looks like the least genuine one for me.

Would love to hear your opinion. Do you think any of these are genuine? And if so, which one would you have picked as real? 

Cheers!
