This might answer your question.
"Precious Metals (including Bullion)
Under the GST Act, gold (99.5% fine), silver (99.9% fine) and platinum (99% fine) in an investment form are precious metals. (Fineness quoted is the minimum that applies).
Under the GST Act, at the time of importation, precious metals are not subject to assessment for, or payment of, GST. Imported precious metals, whether bullion or coins, have a free duty rate, which means no duty is payable.
Precious metals must be in a form that is tradeable on the international bullion market. Precious metals in an investment form carry a mark or characteristic that guarantees its fineness and quality.
Further information on precious metals can be obtained from
http://www.customs.gov.au/site/page5350. asp#e946
Proof coins, other collectable coins and jewellery made of gold, silver or platinum are not precious metals (duty and/or GST is payable unless a concession or exemption applies)."

http://customs.gov.au/faq/ProhibitedRestrictedGoods.asp. How this applies to Canadian coins, I don't know.
Hopefully they would count as duty free. You can see usps.com for shipping rates.
Edit: With insurance for one coin, 2.1
