Anyone can use the PCGS. Its going to cost a lot for one coin. Membership costs $49. They send you a kit to send in the coin. It will cost about $17 to send it and another $17 to return it. There is a fee for the submission. $18 if you put the coin's value below $300 plus $8 for Handling. It will cost you $109 total to get it slabbed and graded. Hopefully the coin was never cleaned or has not subtle tool marks, because then they slab it with "Genuine".
ICCS and CCCS will do the job for much less. Or next time you in Vancouver you will be able to find someone more knowledgable about Canadian Coins and maybe a coin store that will help you out for $25 or so. Plus there are some great restaurants there.
The guys here on CC are amazing. Post a picture. I can't tell you how helpful they have been and how much I have learned from these masters.
