Yeah, but the physical coins are really collectors' items; you destroy the numismatic value if you peel back the hologram to access the digital bitcoin, so I don't know why you'd seriously store funds you intend to use this way. They're a proof a concept; a conversation starter, collectors' item...

For proper safe-storage, use a cold-storage solution like Armory.

And never store more than pocket-change in online-services. Remember, if you do not solely possess the private key, you do not actually "own" or "control" the corresponding bitcoins.
