Topps Stickers

There are currently 204 collectible stickers in the Adventures of Merlin Topps collection, including 160 normal stickers, 20 large stickers, and 24 holographic stickers, all released in 2009. Each holographic sticker displays three different images depending on the angle you view the card at. Collecting 15 of the holographic stickers appears to have granted the contestant a chance to enter a competition to win a "Magical Merlin Fun Day" where you could meet some of "Camelot's most famous residences".
