Ancient coin on ebay [解決]

Hey all, I was on Ebay and I saw this coin, the seller claims it's from 600BC and wanted to know if anyone can find it here and see if it's really that old

This looks like from the Maurya or Nanda empires:

Looks legit, but the 600 BC date seems way too old. I think this is the exact type: N#435866

There are indian punchmarked silvers that are that old, but they look very different: https://en.numista.com/catalogue/index.php?e=india-ancient&r=&st=1-2&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=-600--570&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&se=&c=&wi=&sw=

I think that the seller didn't bother to properly ID it and just slapped a ‘600 BC’ on it because it sounds good. Plus Ashoka ruled about 270-230 BC and is also mentioned by the seller, so there is some confusion here.

I thought that was the case, thanks for clearing it up. Either way it's still 2000+ years old and a decent coin, just a shame the seller put it as an older coin to misguide people
