Question about booster codes

PachirisuFan1

I've noticed that when I redeem codes online it has a note implying an upper number limit, for example for booster packs it shows as x/400 for each expansion. What happens if I happen to reach that limit and then try to redeem one more?

To be clear I am not referring to the max redemption of 10 codes at a time.

You can only redeem 400 of one set. (By set I mean like SWSH Fusion Strike, SWSH Silver Tempest, NOT SWSH itself.) Redeeming more only gives you a pitiful amount of coins. I guess this is to combat bulk buyers.
