<p>[QUOTE="mikediamond, post: 794454, member: 1859"]It's a nice broadstrike with split-line doubling. There is no visible evidence that it was struck more than once. That doesn't eliminate the possibility that it was struck more than once, but one must always go with the more prosaic explanation. Split-line doubling is an effect frequently seen on ordinary broadstrikes and off-center strikes. It even occurs on otherwise normal strikes, although the distance of the split from the design is modest due to the limit on expansion imposed by the collar. Just as split-line doubling is not a reliable diagnostic for diagnosing multiple strikes, neither is the size of a broadstrike. Expansion has very little to do with the number of strikes and everything to do with ram pressure and minimum die clearance. You can find coins struck multiple times outside the collar with very little expansion and coins struck just once outside the collar (die-struck on both faces) with massive expansion.</p><p><br /></p><p>The point is, don't believe everything you read on a slab label.
