Going price for Taobao Prototype Minty?

[MyLittleMinty]

Hi there! I was just wondering what the current going price in the MLP market is for the Taobao prototype Minty! She's been my grail ever since I first saw her online, and I've never been able to find how much they go for. I want to have a goal to shoot towards, since I hope to hopefully add her to my collection someday! I know she's probably crazy expensive, since she's a prototype, but it's good to have goals!

Edit: For reference, I'm talking the early prototype, the one without the outlined cutie mark.
