First off ... Very nice find ... 
Where to start.
In my experience the top three grading companies like getting
submissions in multiple lots. Like 5 coin submission.
I guess you can send in one coin, but I have never tried that.
If you have a local coin shop, they might be able to send it in for you.
Are you planning on sending in just the one coin?
PCGS and NGC will require you to join for a fee.
How much the fee is, will depend on what level you choose.
Without doing the research, sending one coin into PCGS or NGC
Might cost from $60 to $100, with grading fee, joining fee and shipping/ins.
Both do have a level where you sign up for a certain level and get
something like 5 to 8 free submissions.
I think if you join the ANA you can submit to NGC without paying to
join ... But you do pay to join the ANA.
Another option is ANACS. Many hard core collectors will tell you
not to use ANACS, because coins don't sell as high as similar
coins in PCGS or NGC slabs.
But ANACS is the least costly way to get a coin slabbed.
For example for July you can get 5 coins graded for $75 plus
your cost to ship to them.
Also there is a CCF section for TPG grading questions.
You might get more responses post in that section.
