It’s definitely not a class 9, different bust and eyes entirely, plus the legend is much less ‘chunky’ on the 9a1 - you only have to decide which S you have, and then you can decide whether it’s an 8a or 8b
I have to be honest and say I’m not exposed to enough of these coins to make a call either way on what S you have, you’ll probably need to find an identical coin/die, with hopefully the S undamaged. I’m reliably informed that class 8 is a rarer class and a difficult group to collect in better grades, so you might have some searching to do!
