<p>[QUOTE=&quot;Marshall, post: 936575, member: 21705&quot;]It appears to be between 29 mm and 30 mm (29.8 mm is my best estimate from the photos) where a half should be 30.6 mm. It seems proportional to the reduced weight so the metal content is likely the same or very close. I also think they are possibly the same thickness with less rounding or bevel.</p><p><br /></p><p>I&#039;m wondering what other foreign coins were minted there in 1974 with a reeded edge.</p><p><br /></p><p>I recalculated after measuring the difference at 5/75 smaller or 1/25 smaller to 29.376 mm which is far closer to the 29.15 I calculated using 0.0154 gm/sq-mm assuming the same thickness and material planchet as the standard clad half.[/QUOTE]</p><p><br /></p>
