Last year i had bought 3-4 of each of the 2011 coins and sent back the one's with flaws and extras so i ended up with one of each that don't have flaws. I am going to send them in since i have never graded anything before, i don't really care if i lose this first time since i am doing this more as a learning experience. If i get sp69's back i can go over them and look for the flaws that i missed and learn moire about grading and if i get back sp70's i can use them to compare with the next coins i send in.
Here is what is on the NGC website for 5oz. pucks Modern $14 12 working days All US coins 1955 to present. Five (5) coin minimum Note: Five-coin minimum waived for America The Beautiful 5-ounce silver quarters.
Oversize holder is another $20. I think NGC still does the pucks for a flat $20 each with no minimum number to submit.
