Hi all, just looking at this rather nice GVF - EF George ii Halfcrown and the only thing that's holding me back from purchasing is a metal 'fleck' on the obverse. Basically I've never heard of this kind of defect before and I am just wondering that, as a relatively new and inexperienced collector, should I go ahead and purchase or steer clear and stick to buying the best condition coins that I can afford? The defect is reflected in the price but I've bought coins with defects before and regretted it. 
 
	Thanks,
