Yea, it's an off center strike. Not much of a premium since it's only about 5% off center, but still a legitimate error coin
No - it's a slightly misaligned obverse die strike (MAD) - as long as the reverse is normal which I'm assuming it is as you did not show a pic of it!!
It's worth a few bucks, they go on ebay for around $3 (total with shipping) and more. Here is one similar to yours that someone was willing to pay $10 for http://www.ebay.com/itm/Error-1999-...D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
Nay.. I agree with Misaligned Die Strike on the Obverse. You can see a False Double Rim at the 9:00 area of the Cent. A picture of the Reverse would be the best evidence if it shows the Cent to be struck normally. It's a fairly common occurrence and yes it's a very minor Error Coin.
Now this is an offset strike as both sides of the coin have the same offset. Misaligned dies only have one side slightly off and one side normal strike!!
I have to agree with the other fellas on this one, and personally find even a few dollar value to be extremely high. Not that someone couldn't be roped into paying it, but as a general value? No...
