I'm not sure if you mean selling them as a whole collection. If so, first off my advice would be to sell them individually. If someone is really interested in buying the whole collection, they'll contact you to make a deal.
I'd put them up on ebay.co.uk and as you are finishing your listing, you'll get the option to make the listing visible to the USA & Canada for €0.05. Do this as most Central, South American and Japanese buyers use ebay.com.
I'm pretty sure you can use either photobucket or flickr to embed them into the listing as opposed to paying for them. A simple google search should give you easy instructions.
Lastly, MAKE SURE that you use registered post. Buyers can be shady at times and if you can't prove that it was signed for, paypal will always work in their favour.
