You want it Graded?, i can reccommend ACGS - American Coin Grading Service for this coin. they would surely be the company you are indeed looking for as American Numismatics are there specialty and grading is there business.
Then again, perhaps i have become confused an abiguity.. opps. Just having fun.

1. Half Dollar: Dude - we cant take the photo for you. If you want someone here to grade it we will require an image.
2. Isle of Man Silver jubilee 1952-1977, Queen elizabeth ll obverse Value: $5? if your lucky.. metal.. Cupro-nickel (the silver is referring to the duration of the jubilee being celebrated)
This PRO GRADING service would make your initial investment look like chump change. congrats on the purchase. US WALKING EAGLE Half dollars are sooo nice to hold, the Barber Half is harder to get a decent example of but they are simply the best in hand.
