Hey there,
What you are looking for is extremely (and I mean extremely) difficult to find, and if found, very very expensive.
Here is a demo coin:
http://www.cryptonumist.com/coin/s1-1-btc-2011-demo-coin/Note that the demo coins are peeled, but the sticker is still 'there'. Super rare. I might have some.
Then there are 'void' coins, such as ones given by Casascius to a few reporters. They barely exist.
There are also unfunded bars, as well as unfunded gold 1,000 btc coins. These too are very difficult to find.
Then there are of course 'peeled' coins, which were once funded but were redeemed. Sticker may or may not be included. Starting price $500+
