The coin in question looks like a cast counterfeit. The 1921 coins were struck with more care and all exhibit a decent, if not hammered strike. The reverse of the coin in question is way too lightly struck at the very least.
Those raised "lumps" and a shoddy looking rim only add to the dubious nature of the authenticity.
