<p>[QUOTE=&quot;desertgem, post: 2263558, member: 15199&quot;]I would use liquid displacement in a graduated cylinder to find the volume of the coin in cc and then find the density after weighing. I have done this and used a insulin or tuberculin size syringe to adjust the meniscus to a graduated marking to determine volume as close as possible. Remember when doing the calculations to use significant figures, as the lowest resolution ( volume probably) will determine how many decimal&nbsp; places for density.[/QUOTE]</p><p><br /></p>
