I've bought banknotes recently, and very rarely do people charge shipping...even from Sweden/Japan/Netherlands/Hong Kong/China. When people do charge, it's usually only 74 cents. I don't think it would cost $9 to ship something that light. He's probably counter-acting his eBay fees or is doubling his profits.
It has not been going on for too long but Davey is right, it is a huge con on their part (Ebay). You can opt in or out but it saves me "some" aggravation in that I do not have to take to P.O. to get a quote. And that's because I choose not to be involved with all the hassle being a smaller seller out of my basement.
$72 is WAY overcharged for 8 coins. I remember shipping packages overseas over the last couple years that had easily 500-1000 coins in Medium Flat Rate Boxes that costed me only $60 Priority (any country from US). For 8 coins, that should cost no more than 6-8 dollars, maybe 10 depending on the type of shipment advertised. Registered is usually under $10.
Shipping small stuff overseas (to most countries) is very easy. You weigh it and print out a label just like you would for domestic mail. The only difference is that you declare what's in the package and the value before you print, and you sign and date the label. I opt out of the Global Shipping Program because the customers do not understand why they get charged so much.
GSP is perfect for low-medium value items as express delivery, tracking and customs clearance are included. I receive coins bought from US sellers in less than 7 days. No need to go to the customs office and no additional fees. They charge too much for high value items such as gold coins though.
