<p>[QUOTE=&quot;physics-fan3.14, post: 931484, member: 19165&quot;]900, 55 is definitely a fair grade for that nice half. How many lights did you use to photo that thing? I ask because it looks like just one, what James Garcia calls the SOLB method (single overhead light bulb). In my opinion, you need at least two, and preferably three, to capture a coin like that and light the entire surface. That would take care of the darker areas, and I&#039;m guessing more people would have accurately guessed the grade.[/QUOTE]</p><p><br /></p>
