Greenlant, Redwoodrandy is correct in that you don't need anything graded based on your photos. Grading is pretty much reserved for higher-end and older stamps (than you have shown) where the value can vary in terms of hundreds of dollars based on grade/centering, condition, and so forth. If you see stamps on eBay
from 1942 with a Scott value of $.75 graded in 98 listed for $40 or something crazy, that's just a scam trying to sell a $1.00 stamp for $40.
He's also right in that if you want some sort of appraisal/market value; post what you have; although from looking at some of your earlier posts, looks like you've done some research on eBay
