Somebody sanded the obverse smooth then pressed another 2 annas coin into it. Not a mint error.

you just described a brockage mint error where a coin is struck by another coin stuck to the die in the minting machine, this looks like one to me, trying to fake one without a collar would not align with the edge as perfectly as the ops coin

Here is one from a well known auction site

Will thickness not affected. If someone sanded it?

Yes, of course you are correct. My mind wasn't thinking in that direction.
