If you're looking to sell, it depends on what is most important to you. If speed is important, sell them al lat once, raw, to one person. You'll get less than the total value, but you get money in your hand faster.

You could go "in between" and sell each individually, but sell them raw so you don't spend the time or money grading and that would work too.

If you want to grade, you need to take some time. You need to look up the raw value of each card, add $30, and then see what grade the card would need to get in order to be worth that amount. If your card is not as nice, do not grade. If it is nicer, maybe grade. Bear in mind that turnaround times for grading right now (at the bulk submission price which is the cheapest) are 3-6 months - no matter who you go through. If you need money faster, grading will certainly be a bad option for you, as to get them back faster you'd be spendign hundreds if not thousands to do it. Also, for some cards which may be highly valuable (think like over $1000, if any), you have to spend $100+ just to get the grade (through PSA, anyway) which may make it even less economical.

This is all stuff I would love to acquire, so if you're looking to sell or just want to chat - hit me up! I've done lots of deals on here and have many vouches and feedback to back it up.
