As the half cents went form the early 1793 to the latter issues the stock was rolled thiner and thinner and the diameter of the half cent was increased to keep the weight at 6.7 grams. But the weight of a large cent (which didn't change diameter) punched from the proceedingly thinner strip would be progressively lighter. HOWEVER, the chain cents were struck before any of the half cents were made so the idea of a chain cent being light because it was struck on a planchet cut from half cent stock is moot.
