Anyone know the value of Si Te Jiu, a Baijiu liquor from Zhangshu Province in China?

I have this 500ml bottle of Si Te Jiu Baijiu, an old rice liquor recipe, from the Zhangshu province in China. It looks like it’s from 2010 and they no longer make it. Any idea what it’s worth? I can’t seem to find much on Si Te Jiu specifically.
