Brass ungraded will sell for 1.05 to 1.1 BTC depending on the condition and series. Auction is best if you want to guarantee a sale.
Like yim said 1.05-1.1 is what you can expect for price.
Minerjones is great as an escrow for funds between buyer and seller.
You can run your own auction. I'd recommend having a starting bid of face value, and low increments due to the rising bitcoin to fiat prices. Don't forget an end time with time zone specified.
With shipping, depending on country, you'll probably want someone like ups, or fedex. I wouldn't recommend using anything like standard mail via usps, royal mail, etc. due to the risk of package loss.
