I see no reason to think it isn't real.
Those coins were made by the millions (in many variations) and are commonly available. It was probably found in a large batch in rough condition and harshly cleaned.
There are modern copies of some Chinese coins for tourists, but they they commonly have a bumpy background and your coin doesn't seem to be like that. There are also better forgeries of uncommon coins but that doesn't apply here.
I believe this is your coin: N#13110
