[Questions] Not sure how to grade

HI Everyone

First post here, my son and i have started collecting pokemon cards and managed to pull a few rare ones.

Most come from Evolving skies

-Sylveon Alt Art
-Umbreon Alt Art
-Glacion Alt Art

Also have a base set Alakazam and a first edition base set Arcanine

PSA is so expensive and takes so long, so we are looking at getting it graded locally (australia) but i am concerned about the resale value.

We don't want to sell but may need to, to help feed the card addiction :)

Your advice would really help

Thanks

Hey stavros1000,
so, there's alot of Alt Arts. There's the Alternate Full Art version and the Alernate Art Secret versions.
V vs VMAX.

As you said, PSA is expensive. It could be $18-$30 a card and that is if you are a member.
Being a member is like $90/year? i think.

you are hoping to hit a 10 with your cards to get your $ worth, since a 9 is basically kind of break-even, and you mind as well not get it graded.
