I recently ordered some "physical bitcoins" as a novelty gift, and I must say, they're absolutely stunning. At the price they come at they make a great gift for starting a conversation. Hell, you could even try to order a beer with one and it'd be cheaper then paying with real bitcoins!

How do they work, do they have a private key engraved?
It so how do you know the designer/maker won’t sweep them?
