Well, send in the best five first. Or sign up for the annual membership and send in 15 cards, including your Ryans. You'll be able to see what scores high and what doesn't.

Seeing high Buy-It-Now prices is good, but checking completed listings is more important.
I personally wouldn't send in MC/OC cards, but yours do look really nice. The pool of buyers drops when it comes to cards with qualifiers. If you do get some high dollar grades back, you can sell them and use the money towards grading more cards.
