Yes, if I can do them in a laser machine and not have to put a sticker on them, I can crank out thousands of them in a single morning. I can write software to run the laser... and make it so I lay out 150 coins flat, hit start, and it engraves them all with unique private keys in a single batch over the course of several minutes, as well as issuing a script so I can batch-fund them. If I sell the whole thing as a single pack and don't have to deal with stickering or data-entering each coin, the price can come way down.
This technique could be combined with a laser window hologram to restore some security to a circulating coin (although an xray or other electromagnetic imaging could reveal the privkey (note, even laser toner could fall to the dedicated observer, though)). Laser both the public and private on the blank side, and position the window to reveal the public string.
You could roll your own "gift" coin, if you are a betting man. Give them a two year expiration date and recall them yourself, in exchange for selling at face value or barely more. Coins may be fun to give out as gifts or promotions, but you never know if they are being circulated, stored, or found their way to the dust bin.
On a previous comment, I don't know that even a 0.1 BTC coin should look cheap, it's worth 4.5 x more than a US dollar coin.
