Here something you don't see every day, especially in the Indian series. To top it off, it's certified by PCGS!
Seems to be on the right planchet type, but a defective/rolled thin copper planchet. Can you show the holder?
Looks like broadstruck and then suffered post strike damage. Unless the weight is wrong the planchet looks right.
Looks like copper to me but the planchet looks as if it suffered damage before striking occurred. Nice coin.
