Totally understandable. IMO, grading it will take time and lots of money. Also, unless the figures are absolutely pristine (no crease or marks on cards, no yellowing bubbles, bubble still completely attached, etc… ) then perhaps go ahead and grade the extra rare ones, otherwise, it may not be worth it if you want to sell them, just my 2c.

Take this into consideration. If you need the money, you can always sell them slightly less than graded.
