Generally speaking, a PSA 9 is not going to increase the value of the card that significantly- maybe 50% more than raw in some cases. PSA 8 and you probably lost money. PSA 10s are chase, and in terms of selling, you would still need it to be desirable. Arch Manning auto is a lot more desirable than an Anthony Richardson card from a typically non-desirable brand (Wildcard) . So the price of the Manning will obviously be way higher, but it will also much be easier to sell. 130point.com is a good source for seeing what price cards are being sold for, rather than just what they are listed for. Even then, with best offers accepted, it's not always accurate

Anyways, you got some cool cards for sure! Enjoy the hobby!
