This year I gave out physical bitcoins in the form of Satori Bitcoins. If you have not seen them, they are available on Ebay. They will not only grow in bitcoin value, but in Numismatic value as well. make sure you get the Pre-Fork ones so you get B-cash and all the others. I got rave reviews for this as a gift. Merry Xmas / Happy Birthday whatever. Enjoy.
Here's a link to what I'm talking about.
