Hi Joc. The short answer is .. probably not. Quality control isn't great at the mint and odd blobs of metal appear occasionally in places they shouldn't! However, without actually seeing pic of your coin it's difficult to be conclusive. Some people collect what are called 'error coins' and some are more interesting than others. You can add a photo (ideally mostly of the coin rather than background and in focus) of 100kb or smaller directly to a post by clicking on More Reply Options. Or if you have pics hosted somewhere like flickr or photobucket they can be linked using the little icon that looks like a picture of a tree at the top of the reply box. Then we can probably give a better answer. In the meantime, welcome!
