Apologies if this has been answered, I searched and didn't see anything. This is my first time submitting a comic and I am not sure how to know which tier to choose. Even checking eBay is really reliant on what grade I end up getting; it MIGHT be worth less than $400 (so Modern tier), it might be worth up to $1,000 (so, Standard tier). If I submit under, say, Modern and they determine it to be worth more than $400, what happens? Do I just get told "Hey, actually, it's worth more and you have to pay us the Standard fee now" (which I am totally fine with if it ends up being worth that) or does it just get returned to me ungraded, or what?
Thanks!
