I see the picture. And you are looking at recently sold prices... perfect.
LE 2000? LE 2000 is not really that rare. That said, sometimes large edition sizes or even OE become highly sought after.
Another factor: live action movie pins... usually live action pins are not highly sought after.
This is also a sequel... in general sequel are typically less popular and so are the pins.
The pin has a date on the front... also another factor that can bring down pin value.
All the above said... I am not familiar with pin values on High School Musical. So the above are general thoughts.
I didn't find any sold eBay listings either. But found two active listings:
<p>Official Disney pin Trading high school musical 2 premiere pin </p><br /><p>LE2000 (unnumbered)</p><br /><p>Year: 2007</p><br /><p>Some yellowing as pictured from aging of the epoxy over it, but otherwise no scratches or wear</p><br /><p>Kept safe and dry in official Disney pin collecting...

High School Musical 2 - 2007 Premiere is a Limited Edition (LE) 2000 pin from the High School Musical Disney pin series. It was originally released on August 17th, 2007 and was available from Multiple Sources (WDW, DLR, etc.).

The fact that these high priced listings are
not sold probably means they are over priced (I think... very over priced - but this is a biased opinion from someone who doesn't care much for putting dollar values on pins.) Perhaps, you price your pin at $50 and someone might think it is a deal (ie, these other two listings make a $50 pin look great.) And you get it sold. My rough initial thought tho... this pin is worth about $15.
That is my bias thought process for this pin. For whatever it is worth... Good luck!
